Forced to return my cat to the shelter due to OCD

NSFW 17f So basically I did something sexual to the cat when I was younger. It wasn't like full on bestiality, my privates weren't touching the cat and I wasn't touching the cats privates but it was still sexual. I didn't know what I was doing was wrong. It didn't harm the cat in any way, but of course it's still horrible. So I developed real event ocd that ruined my life complitely. Most of the time I don't think I will male it to 20. Sometimes it's a living hell. I developed it more than a year ago and I barely even remember this year cause I was so consumed with guilt it was the only thing in my head. So i also developed zoophilia ocd because of it. And I feel so bad cause I can't interact with my cat anymore. Because she wants to and I have to ignore her. Slowly I started to be scared to let her on my bed. So I stopped. Then in my room. Stopped doing that too. I still tried to give her some attention just outside of my room. Then I got scared to touch her. So I stopped doing that, but I used her brush to pet her with it and her toys to play with her so i don't physically touch her. Then my ocd went like but what if you are subconsciously using her for sexual gratification when you look at her? So now I can't even look at my cat. I look away when she is around, block my sight with a hand, close my eyes or if I can I leave. But the heartbreaking part is. Before I remembered what I did I was giving my cat a lot of attention. Like everyone says I'm her favorite and she only allows me to hold her and pet her the certain ways. So for all that time she is desperately trying to get my attention. She jumps on my rooms door, meows for a long time, tries to sneak in my room and stuff like that. And It's so sad I just have to ignore her. Especially cause she doesn't understands why. She was getting so much love and then randomly she is being ignored?? idk her real age cause we took her from the street, but she lives with us for 13 years, so she is not young. She is pretty healthy so I don't think she is going to die any soon but still. if I never get over it she will spend her last years of life ignored. and this makes me want to cry and want to throw up. but I don't know what to do. if I touch her I start freaking out and convincing myself that I used her somehow for sexual stuff even if I didn't do anything like that. I'm so scared. and also sad for her. and I miss my cat tbh. like everhtime I have to close my door when she tried to enter I feel so bad. but I'm so scared. because after what I did to her I'm already a monster. I don't want to add anything else. but I also feel bad for ignoring her.

tw: nsfw 17f I have a real even ocd from a sexual event with an animal (my cat) from where I was younger. Remembering it ruined my life and made it a living hell. It was bad. It's not one of those innocent events people always assume because I have ocd and then they get all surprised when it was actually bad and sexual. (animal wasn't harmed though) So basically I developed I fear of interacting or even looking at animals after I remembered so I was avoiding my cat like crazy, but then I realized that it's cruel to ignore an animal who wants love and attention, so I forced myself to overcome it kinda. I basically downloaded a habit tracker where I mark when I was able to pet my cat cause while it's triggering I want to give my cat love and I'm trying to pet her everyday So yesterday I was petting the cat. And she was extremely enthusiastic about it. Like she was almost throwing herself on me to get more pets like kinda agressive at this point to get pets. I started thinking how animals go in heat in spring. But she is like sterilized so I wasnt sure its possible for her. Like maybe they are just more active in spring? But what if the pets are somehow sexual for the cat? Then I thought maybe I shouldn't pet her then cause that's wrong. But then I thought like who cares and also then it will be like this the whole spring should I just not touch her the whole spring and ignore her again? I was also tired a bit so I wasn't thinking it all through that much Now I'm freaking out so bad. Like I knew there was a possibility that it was sexual for the cat and still continued petting her I didn't stop. It's so bad. Like I thought its whatever since it's not sexual for me but now I'm freaking out. Like the whole me being a better person and learning on my mistakes after that one earlier event was for nothing if I was able to do something like this I'm freaking out so bad

I will preface by saying I am not diagnosed OCD, as I can't afford to see therapists or psychiatrists at this time. But given the things I've gone through, I'm pretty much convinced it's what I'm dealing with. I never really saw it coming. As a kid I always had health issues. Sick all the time, spent a lot of my very young years in and out of hospitals. In recent years as I've become an adult, health anxiety started creeping in. I spent my teenage years depressed, anxious and suicidal, both passively and actively. I engaged in self destructive behaviors in an attempt to end my life quicker. I left a toxic home environment and began my journey to improve my life, as I have a significant other that I want to stay on this planet for. I began lifting weights and exercising, eating better, and attempting to improve myself day by day. I didn't even realize it happening, but over time I started caring more and more about my health. Avoiding certain foods, making my diet stricter, and ensuring I did the right things. While it was good for my body in the short term, long term it seems it really affected my mental. As I started to feel better, I noticed that the times where I wasn't feeling 100% were very stressful. I'd start to worry about developing diseases. Diabetes, appendicitis, cancer, any number of rare and deadly diseases i could discover on Google. It got worse and worse as time went on. I'd spend money on things to test my body. glucose monitor, thermometer, supplements to ensure I was healthy. mental compulsions began (which i didn't know where compulsions at the time). Well, it all culminated at its peak in the last few months. Every minor bodily symptom, no matter how normal or common or frequent, became a life threatening warning. Constant googling, ruminating, checking and reassurance seeking, which at the time I didn't know was what I was doing. Then, at the end of May, I did get sick. And suddenly all of my obsessions and compulsions solidified themselves as real and premonitions that were true. I started spiraling. Avoiding social events, or anything that was outside of my room. Barely managing to go to work some days. Bringing my compulsions to work as well, sneaking them in when I could. Every day was anxiety riddled. I became exhausted. Sleeping for 10 hours, waking up still tired, coming home having no energy to do anything. It convinced me even more that I was getting sick again. I was getting suicidal again and contemplating it very often. I then noticed my Instagram feed getting filled more and more with OCD related posts and ads, I guess i was unconsciously finding and engaging with them. They described exactly what I was going through, and still am going through. I'm on day 4 of my recovery after learning some ways to help myself. I'm catching my thought patterns, learning to allow the uncertainty, and avoiding my avoidant tendencies. I removed the batteries from my compulsions and put them out of sight. I still am learning my mental compulsions and how to deal with them. I'm engaging with the things I would avoid now despite how I feel. I'm still riddled with anxiety and the OCD thoughts are very loud and frequent. But I'm feeling more in control and like I can handle the thoughts better. I'd love any advice people can give as well. I want my life back.
