Any resources for transgender ocd? Anywhere?

I'm starting testosterone soon and suddenly I'm feeling more anxious about regret and being wrong. I was on reddit (that was my first mistake) and a post popped up on my feed and it was a cis woman saying she did some soul searching and realized she wasn't a trans man after all. she said that she was a tomboy growing up and dealt with trauma that she needed to detach from. it shook me a bit and now I'm scared that I'm making the wrong choice. does anyone have any tips to get rid of this constant doubt?

I can't look at 18+ videos, comics, etc. I am straight, but SO-OCD tries to make me think I am not And the thoughts turns to feelings, and makes me scared, uncomfortable, sad, because I know this is not me. And when I try to imagine myself being with the woman on adult videos, and comics, my OCD gives gronal response not at the girl, and it fills me with fear, and anxiety, I always loved, and was attracted to women but I can't and it caused me to be depressed, and I keep ruminating I keep trying to focus on her, but it's so bad that I avoid those all the time now. I am wondering has anyone gone through something like this, or currently is, and wondering how you have done to combat this!

2 nights ago I saw something on my phone and it has now spiraled into me scared of being trans or being gay because i don’t want to be… now i have a huge fear of what if i am gay and am attracted to woman or what if im not comfortable in my body and want to turn into a man. It’s freaking me out - my ocd always makes me question my character! Has anyone experienced this 😩
