Idk why i dont care about anything except staying home and gaming.

Iv been like this ever since i can remmember and with time i started feeling more isolated and the only thing that i feel my brain wants is being alone and being angry idk why.i always feel anger and sad and my brain likes it.Its really funny and surprising that im like that.im in my last teens and have nothing.honestly i tried my best to get out and have a job but i always feel what im doing is useless and has no meaning to me.Im very ashamed of myself but i cant change.I would like to know is there anyone going through this as me?i feel soo strange iv nvr met anyone like me.
