I had an emotional break down 😢😂😭😿

this has been on my chest and I need to vent to somebody but going on the other day this boy was like blocking my way in the hall I told him to stop he did then he put a desk in the way and I threw it I then realized that it wasn't a good idea to that 😂😂 I've had many situations like that with him before and I realized that when I get mad at people I lash out at them for other things that have nothing to do with them but going on my teacher told me to go to the office she started asking me questions telling me I've been acting different and I just broke down I couldn't control it I just vented to her I told her personal things about my family that I've been holding in for years and she called the police as protocol I felt so bad and now when I speak to my family it's like an elephant is in the room idk what to do just felt like then would be the time to just let everything out
