So im 16 old gay guy and I dont know whether or not Im trans or if its just tocd. Last week I thought popped into my head "What happens if I were trans" and ever since then I haven't been able to stop thinking about it. Ive started to question everything that I've ever felt even thought I've never felt like I wanted to become a girl. I've never really wanted to have boobs or a vagina or even wear girls clothing. I wasn't really interested in any of that, and then since last week ive been questioning everything that I once knew. I've always wanted to have a beard and never looked at my penis and thought it was disgusting. I feel like im losing myself and everytime I feel that I'm trans I get scared and I dont want to feel that way. To put things into perspective in November I got it in my head that I had cancer, I was so sure I had cancer for at least 2 months until I went to 3 different doctors that all said in their professionial opinion they were sure I didn't have cancer. Even after that it took a while to accept it because in my head I was thinking that doctors can make mistakes. But back to me thinking im trans I feel its gotten to the point where I think im in denial even thought I've never wanted to turn into girl.Its also gotten to the point where I'm waking up in the middle of the night in a cold sweat fearing that I might be trans. I dont know what to do. I've told my family how I've felt about this whole thing and they've all been supportive. My brother suffers from OCD as well and he's sure that what I'm going through is a form of OCD as well but my family says even if it isn't they'll love me either way. This comforts me for a while but then I start getting anxious and nervous again and start questioning if im trans or not. the worst its gotten is when I realized I've never been in a relationship with a guy and then i started questioning whether or not im really gay guy or if Im a straight girl. Please help I've been worrying about this for a week and its been killing me.
