How can I cope with intrusive thoughts in a new relationship?

Looking for opinions please. Suffer from Intrusive Thoughts related to speed (not the drug) due to past trauma as a child. However, experienced something different and peculiar.  I have been with my girlfriend for 10 + years, she's funny, beautiful and very sweet. I admit that I plan to get engaged end of the year. I recently returned from a trip abroad with my family, then soon took my girlfriend on a trip that involved a long arduous drive. On the day we returned we sat with her family having a nice time (even if I was a little tired) and suddenly a thought hit me from nowhere (paraphrasing) "you're laugh is annoying" or "you're not likeable". I was so taken aback that I even thought this. I love this girl, so where did that even come from?! Because of these kind of thoughts, I started to have an anxiety attack that I attempted to conceal from those around me. I felt sick to my stomach, sweating and even moderately shaking. I'm sure you all know anxiety, so I won't detail it further. But the idea of these thoughts still churns my stomach. Whenever I see her now I feel guilty, I feel anxious that I'll think something like that again. It's a vicious circle of course, the more you try to avoid these things they seemingly get worse. Is this even something related to OCD or Intrusive Thoughts? Usually such thoughts are images, not this. I have been looking up online what it could be, even considering whether it's voices in my head, afterall I don't know what that would even be like. I feel dreadful about it, I want to propose to her but she deserves better surely. Really confused and ashamed. My other intrusive thoughts are not like this, nor related to anyone. Would appreciate your thoughts. Thank you.

This shit is RUINING my relationship! I’m so FUCKING done with this. I think I have trans ocd but my past actions are messing with me because a couple of times in the past I said that I was trans. Like without thinking. And I’ve joked about being a boy in the past because I’m not very girly. I’m a tomboy. I’d say I was trans because I somehow thought it was cool or something. Well I’ve never hated being a girl. As a kid I was really girly like REALLY girly. I hate the thought of being trans and right now I’m going through so much anxiety. I have a boyfriend and I love him a lot but if I do turn out trans it will ruin everything. I never lay awake thinking about being a boy. I never cried or was sad because I’m a girl. I hate myself for saying these things when I was younger because now I’m so stressed about it. Please help. Am I trans for these things? Because I used to think there might be a possibility or myself being trans because I was kinda tomboyish but I never worried about it. It was just something that crossed my mind. I liked dressing masculine and looking masculine too. I remember when this whole ocd thing hit full on I clearly remember thinking “ohh this is really similar to when I had murder thoughts”. I really hope it’s ocd. Fuck this is ruining EVERYTHING. I hate this so much.

Guys I'm really scared to talk about this but it's taken over my life at this point. Occasionally, I would get an intrusive thought that would be kind of racist and I'd be scared or I'll sit and think for like an hour of past situations where I may have been racist. It's terrifying because I talked to my mom about it and she laughed because she said I'm like the opposite of racist which I'd like to believe, but these thoughts are so triggering especially because I am also in a biracial relationship. I would never want to hurt him or make him feel lesser than me. I wanna show him off to the world but there's this put feeling in me like, what if you're only doing all this for him not to be perceived as racist? What if you don't actually believe in being with him and you're scared to show him off? Are you afraid what others think? And then I try to prove the thoughts wrong by disagreeing with them in my head and thinking about the past situation. I try not to compulse while with my bf because the last thing I want him believing is that these thoughts are real and are gonna make me treat him differently. Someone pls help like I can't keep thinking of the only person I love like this.
