You don't know what it's like to do nothing! I mean, I want some normal work to do so that I'm not wasting my time here. To learn stuff, build new skills.

I do know what it's like to do nothing. I don't know how you've lived your life until now, but I bet this situation is new to you. You'll have to learn how to fill up your time with meaningful things despite of negative thoughts overflowing your mind. You should one of this days sit down, put down the cellphone somewhere it doesn't distract you, grab some paper and a pen, and write down how you feel. You'll see that writing down your situation and feelings will help. Don't underestimate the time needed when doing this, and don't think it'll be easy to find something worth your time. And lastly, don't hesitate to try new things, unless they're drugs or alcohol.
