Pocd ! Want help or suggestion

I can't do this anymore I feel fucking insane my mind keeps telling me I want to k word people and if feels like my mind is making fucking plans. I'm diagnosed with ocd but I don't even know if it's ocd what if I'm just a terrible fucking person that actually wants to do this. My mind is literally telling me to go buy a weapon and hurt people like I get fucking urges. I can't keep food down and have not for the last few days I feel like I need to go to a mental hospital but I don't want to burden anyone in my family. Like my mind tells me specifically I want to do this but I don't want to but recently ive been having the thought of what if I did do it but I don't want to. I just want it to stop I'm a good person I don't want to hurt anyone at all. But what if one day I actually do want to do something. I can't do this anymore.

I’ve been feeling really really depressed the past few days due to health concerns. I’ve been really feeling down like not wanting to be here anymore and it’s scaring me. I was in the doctor’s office this morning and I got a scary thought that said maybe I should just k*ll someone in here instead of k*lling myself. Then the thoughts continued… this man walked past and I thought “hurt him” I obviously wouldn’t want to hurt anyone let alone a bug on the sidewalk, but the thoughts began to overtake me and I had a panic attack. It’s still bothering me and I’m still scared it’s real and that I’m going crazy. This happens to me a lot after I watch a documentary about someone who hurt someone else. I begin to think I am somehow going to go crazy like the person in the documentary and hurt someone. Although I don’t want to .. I would never ever want to hurt anyone.

POCD has been the worst thing I've ever been through. I feel like I have always sort of experienced it but not to the degree I do now. I used to plan being a mother to a beautiful family. Now I don't know if I'll ever have children at the risk of having a girl. I used to have intrusive thoughts that would make me feel weird but I could just move on from them. That was until I had to babysit my niece and change her diaper. I want to throw up thinking about it. I got a horribly strong groinal response and I didn't know what to do. I didn't understand why it was happening. It bothered me all day that day and later on I did the disgusting deed of testing myself. I regret it everyday. It's a horrible compulsion and it haunts me. I tested if I was getting off to the thought of her. And of course there was stimulation because of the groinal response. But I hated doing it. I just felt like I had to be sure. After that and since then I haven't wanted to be around her. I stopped planning being a mother, I stopped watching cute baby videos like I used to enjoy because they trigger disgusting intrusive thoughts. After a while I stopped being intimate with my boyfriend and haven't done anything with for months because the thoughts take over and make me feel like I may enjoy the deed more if I was thinking of children. I worry that maybe I do enjoy these thoughts and I'm just denying it. I wish I could be sure. I feel so disgusting and ugly, I've never hated myself this much. It takes over most of my days. I wish I had never changed her diaper. Some times in moments of clarity I am so sure that I'm not a predator, but when I am vulnerable OCD sneaks back in and tells me I enjoy my thoughts and that I should think them. Sometimes it gets so overwhelming that I have to test. I wish I could stop. It ruins my entire week. I feel like a monster. I want to love my life again. I miss life before this. I feel so hopeless most of the time and I can't imagine a way out. I'm scared to start therapy because what if I found out I am a monster? I can't live like that. I won't. I want to cry and scream. Am I alone in this?
