question when it comes to old thoughts resurfacing

Hi Everyone! I hope whoever is reading this is having a good day so far :) So for years now I’ve had very bad intrusive thoughts about things that I have done or embarrassing things that I’ve said or have happened and it’s mortifying and debilitating on a daily basis. Specifically these thoughts are mainly things that have occurred from 2018-2020 and some are more simple just as a stupid joke I made or being way too loud on calls while my family was trying to sleep and others being way more complex such as past relationships and how I’ve hurt some of the people I care the most about and when I have acted on intrusive thoughts and these thoughts will appear with no triggers at all I’ll just wake up and already have something I did just nagging me. I don’t want to live like this anymore and I’ve tried working through it with self compassion but sometimes the things I said or did back then it’s very hard to forgive myself for and I’ll reminisce on it for hours on hours, gaslight myself into believing that’s not how it happened and try to change the memory itself, or just suppress it entirely. I know those habits aren’t healthy and truly I want to get better but I don’t know how to overcome some of these thoughts. I have talked to my fiancé about this a few times and even today we talked about it and he fully supports me and is helping me work through it. I might also contact my sister too, I don’t talk to her overly too much but ever since I was little she’s thought I’ve had ocd and was one of the people who made me consider that I might have it (I’m still undiagnosed but I’ll try to when I have the money and time) and I know she could maybe provide some insight. Another thing that is troublesome about the situation is my other family members specifically my mom aren’t the most helpful and can trigger thoughts. To put it in perspective on how her thought process is and some background info she is an ER nurse and has been for 30 years due to this she believes she knows mainly everything there is about mental health and she gets extremely upset when I don’t take her advice or set boundaries. She’ll force me to talk to her about my problems and when I don’t want to she’ll pin me in a corner where I’m forced to and last summer I had a really bad episode and was really overstimulated and I just finished taking a shower and due to the water on me, my hair being wet (my hair is naturally curly and it takes forever to dry and it’s very draining taking care of even with a keratin treatment) and all the intrusive thoughts I was having and she forced me to talk to her and I did open up for the first time about my thoughts and brought up how sometimes I have thoughts of hurting my animals and it makes me physically sick. Her response to this was threatening to call the cops on me saying it was a behavioral thing and I was doing it for attention. I have never hurt any of my animals but later that day my cat came into my room and a few minutes later she comes up just gives me the death stare and after a few seconds just asks me “are you going to go kill snickers?” In the most condescending tone and she’s always like this daily where she’ll force advice onto me or get upset and yell and then reinforce thoughts I’m having. I just want to know first how to stop the thoughts from so frequently and how to heal in an environmental where it keeps reopening wounds despite trying to place boundaries? I’m sorry this is really long I usually do go really in detail about things and it’s just how I’ve always been. If anyone has any questions feel free to ask and I’ll answer them to the best of my ability. I really appreciate the time you took to read this and thank you for your help! 🥰

So recently I have been talking to this guy and I really like him and for the past week I felt really good and happy about it, but then a sneaky intrusive thought popped up about what if in the future when and if the time comes to sleep in the same bed, I inappropriately touch him while he’s sleeping. Now I’ve struggled with sexual intrusive thoughts like that before so my brain just kept reminding me of how that thought felt the last time it came up, and the thoughts of sexually harming this person started snowballing and making me feel worse and worse. I spent most of the day crying and panicking wishing my brain could just shut down, and now all I want to do is hide from this person so I don’t get the chance to hurt him, which makes me feel even worse because I had been feeling so good about him just the other day. I was just wondering if anyone else had experienced this and if they might have any insight

I feel like it’s just me. But at night when I start to fall asleep, play on my phone, or watch TV; I’ll get major intrusive thoughts and a butt load of anxiety. Has anyone felt the same about this? How have you managed it? It’s getting exhausting and even causes me to sleep-less.
