Idk if this is the right place to post this but im always mad and i dont know why. its hard for me to be happy because when i am then everything just goes to shit. my family always tells me im always in a bad mood and that nobody does anything to me so i have no reason to be like that. i dont even talk to them most of the time because when i do i get ignored. And sometimes  its not even that im mad i just DONT have anything to say to anyone. nothing exciting. I start being a bitch when they keep bothering me when im clearly not in the mood to talk and just answer with a bad attitude. Ill get mad at small things like someone knocking on my door, someone phone volume being too loud or someone staring at me while i eat(or in general honestly). Theres time where ill also bump into something like stub my toe or whatever, and ill start throwing things or punching the fridge like wtf, what did the fridge do?? theres reasons why im mad but its stuff that im mad at myself about so its not a reason to lash out on them. For example ill be chillin then ill remember things from my last relationship and just be fucking pissed all day. Just want to be left alone all the time. Is anyone else like this? Could it be BPD? I do feel bad afterwards because like why am i so mean? idk whats wrong with me im not like this through text
