Am I just searching for attention ?

Im fucking going crazy , two days ago I had what can only be described as a manic attack , for no real reason , I saw a couple friends smoking outside and they didn’t invite me even tho they said they would and after deciding to go out my motorbike broke down , I went home and just let some anger out on a boxing bag and took a stroll through the city to calm down , ended up punching a trash can and my knuckles got super awaken , I’ve also cut myself for the first time in my life , and after all this I can’t fucking understand weather I’m just overreacting or searching for attention
