Im getting triggered with anxiety about everything now, even things that i enjoy trigger me. Idk what to do anymore

Idk anymore it feels like being on here is a trigger. Every time I see a minor post on the app, my intrusive thoughts go haywire and then my brain says maybe you should comment something inappropriate and i literally don't wanna fucking do that. It's the last thing I want to do. And now im scared that I commented something crude on someone's post. obviously, when I went to check there was nothing now my brain is saying "you commented and then deleted". I want to think it's something I wouldn't do, but why are the images in my head so real. Children should be safe. I feel like I need to be locked away. Someone please help me.

I'm at my college and don't feel like being here. I didn't even want to come here. I woke up with anxiety bc i feel like i need to solve this. I had a bad stomach ache when i arrived to school and still havent even eaten breakfast yet bc i feel like i have to solve this. Im just so worried bc i have harm thoughts daily. If i could i would remove this! I dont want to think anymore. Its just, how do I know i dont have real urges when I'm feeling a negative emotion like anger or disappointment or annoyance? Im worried EVERY time i feel a negative emotion. Yesterday I was playing video games with my neice (we are close in age range) and she made us lose. She started blaming me and I guess i felt a little annoyed, it really wasnt my fault (dumb mini argument it was more playful since we started laughing but it was a bit annoying). Anyway i got a harm thought while feeling annoyed of me getting off the couch and lunging at her to attack. I immediately look at my bodily reaction and I tense up to stay as still as possible. My stomach was hurting and i wanted to leave as fast as possible. I stood up and turned off the game and said i was tired while making sure to stay back from her (and i had my hands away and stiff) but i felt so uneasy. I laid I bed and felt sad and heavy. And i kept getting thoughts that said "íts only a matter of time before you can't take it anymore". I started to reassurance seek using ai to ask if i was about to or if they are real urges or thoughts i mean until i eventually fell asleep in the middle of the compulsion. Im just so worried, what if I act out impulsevly one day? I dont want to! But what if when feeling a negative emotion, i suddenly dont care and do something? I really dont want to! I dont even want to feel negative emotions anymore since they trigger the thoughts and I dont want to think about any of that. As a result i tend to avoid my family as much as possible bc they are annoying sometimes. I just wish i was all alone sometimes so i wont get any more thoughts and so everyone can be safe. I usually just stay in bed under my blankets all day long to avoid my family and pets. I am constantly uncomfortable. I miss when i would never think any of this. Living life has become very scary for me now. 😞

im so scared that this is just denial and that im actuall gay. idk what to do anymore i need help. its just constant anxiety in my chest and i hate it. is there anything i can do to help?
