I feel so empty

Every day I feel numb. I count down the days to any little social interaction (even going to work) because thise are my only source of "joy" now. I talk to people online, but i end up ghosting them because i get bored and tired of interacting. Even fun shit like smoking, or getting high. Ive even stopped cutting because it brings me absolutely nothing; no joy, no pleasure, no feeling of punishment, absolutely nada.I considered ending it all but I dont wanna miss my 18th birthday next year so I cant. I plan to go to a hardcore concert so i can get my shit kicked in, just so i can feel something. Im Actively looking for a therapist, and igot a psychiatrist so I dont need any professional advice. Im just wondering if theres any activities I can do that might be entertaining enough to keep me engaged and like, actually happy
