What is going on anymore?

I dont know whats going on anymore i dont understand what the **** is with my head idk. Im different now, and im not the same person i used to be. I dont do anything, just stay at home play games, then watch some movies, go to work, and have 5hour sleep. Im 17, i feel forced to talk at work, everyone i normal and im not its obvious, i just rather sit there and not talk at all. But there is 2 of us or more and they will say im weird, im tired of some **** talking about his god damn car or life or his kid. It feels forced. I dont want to do anything or work, i dont know whats happening to my stupid head. Its been like this for 3 and some years ever since the panic attack, nothing has changed, im not interested in anything other than staying alone or just doing abnormal stuff. I am weird. Im become a weirdo no, the quiet one.. I dont understand i try evrrything, the only thing i like to do is play games or stay on the internet or talk to her in camhs, but she will leave me soon and everything will end, i will have nothing to do and no point to everything.... Its been over, 3 years i dont understand it. I just want it to end.
