i have to take this psychology class for my major and its developmental so we talk about minors and it triggers me so much but what else can i do? i just sit here uncomfortable and anxious

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. 😞

I'm in college and about an hour ago i had class. I like to sit alone bc I get a bunch of stupid intrusive harm thoughts. Anyway I couldn't focus AT ALL today. This girl decided to sit next to me and I wanted to ESCAPE. Like i desperately wanted to get up and leave to the bathroom and wait till class was over. I took a deep breath and stayed anyways and tried to focus on lecture but i kept getting so many thoughts and I kept hyperfocusing on my right hand (which was next to her) and my hand felt so weird! Like tingly?? I was like "omg why is my hand feel so weird?? Does that mean i want to do something?!" And it kept imagining me grabbing at her or grabbing my drink and throwing it on her while i was trying to take a sip. I tried eating my breakfast to distract myself but i was holding a fork and got another thought. I realized i was tensing my hands (as a compulsion... i try to keep them as still as possible and as close to me as possible bc the thoughts feel so distressing and the "what if i act out " is playing in my head) And I was internally panicking and now im at the library feeling sad and i feel like I need to solve this. I spent the past hour just mentally reviewing the whole class time rn. The whole class time I was at the edge of the table trying to stay as far as i could and i would get relieved whenever she would stand up to leave the class for something. I managed to make it through the whole class without leaving though but the question in my mind is bothering me so much, "how do I know that these thoughts aren't genuine or are thoughts I want to carry out and why was my hand feeling so weird?" I feel stressed at the library and i want to figure this out 😞

I dont want my relapse to stop me to assist, I will go but I am sad because I don't want a beautiful moment to became horrible because the fear and dicomfort I am feelling this days. It will be a good exposure but how can I enjoy it? The depression came back, I wasn't prepared for this, like I knew OCD is chronic but I forgot it hahaha Right now I am trying just to think in short times like, 24 h and it is helping a bit Update: The day was really good !
