Time to man up basically, get a job, drop the excuses, just man up.
It's weird that they dropped you just because you are not a total loser...
If they decided they can help people who are in a worse situation then you then you have no excuses to waste your life. Finish your highschool(?) and get a job before it's too late. You are only 17 after all.

Don't worry, you have plenty of time to fix your life in whatever way you want it to be. Another piece of advice i can give you additional to those before me is stop sitting on a chair all day and start exercise. 5 mins a day and you will feel much much much better. Breath the beautiful clean rural air full of oxygen. Many people cant find that oppurtunity. I believe there are also other possibilities like you can go for like organic farming in a small space (if you have the oppurtunity) or stuff like that. Or mountain/nature watch if there is such a thing in your country. Payment may be poor but sufficient to live, and you would be all alone, happy and free in the wild.
I havent mentioned everything relevant to this, because it is personal. But i appreciate what you have all said.
Cba to quote first paragraph....but the short answer is this:
I'd kill myself....fast and sudden. But hey, that's just me. If 30 minutes go by and I notice I completely wasted time, I immediately go crazy.
If I were u, i wud rather commit suicide.
