Pissed off at everything

Currently im pissed off at everything. Normally im always trying to be rational, but i really just want to shout at people or punch their faces in. Im pissed off because im realizing im finally mentally healthy enough to do all the things "normal people" do, as in going out, partying, socializing and so on, but all my friends are working now and everyone my age became intensly boring just standing around in closed groups of 3. My trainer doesnt adress my problems in training. Training itself pisses me off rn because my forearms hurt like a bitch and i cant bench and do my hobby that i love like i want to. Im pissed off because everything just seems like i already know it and its an old boring script. Even trying out new things is fun for a couple hours, after that its boring. And im pissed off because im off my meds for 2 Weeks already and probably will stay off my meds for over a month additionally, because nobody is at the doctors office. All that right before my "finals" that i for once in my life wanted to do while being medicated, but as it seems im not gonna get meds until after almost all exams.
