Y’all ever see the Tik tok where it says “I ain’t ever seen all straight siblings?” It has me freaking out rn — someone help

About two hours ago I saw a tiktok of someone who was about level 2 support level for their autism and isnt able to go to school because of it among other things, and ive been freaking out ever since i frequently obsess over mental illnesses or physical illnesses and thinking I have them but one im actually pretty sure of me having is autism but seeing things like that makes me think that im wrong, that my family members are right with saying im just special because i feel like i do not struggle enough, if that makes sense, my friends believe that it could be a possibility, but im not sure, i dont know how to calm myself, no one is responding to me right now and everyone is busy im just struggling

I used to never have these thoughts it feels like im a different person and im so sad . I watched a TikTok of a girl with her kid and my Brain says how has she not killed her kid yet like wtf cus I get so many thoughts I’m shocked other ppl don’t and now my Brian says how I have I not hurt my dad . I keep posting and I shouldn’t but I feel not normal

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 😩
