Spritual, the problem with you is you think too damn much. You don't have to do what I say but for just one day, say FU*K YOU to everything. 

Say FU*K YOU to that guy who makes more money than you.
Say FU*K YOU to those friends who eat away at your soul.
Say FU*K YOU to those Americans who think they are better than you.
Say FU*K YOU to everything you don't like and agree with.

It is a big world out there. Don't be scared. If you have crappy friends, let them go. A lot of times, we hang on to people we don't like because we are scared we might end up alone. I am telling you, crappy friends will kill you. And stop thinking about what is gonna happen in the future. Nothing in the future is guaranteed. Just give it your best and work towards it but don't let it drive you crazy just thinking about it. 

Say FU*K YOU more often. People might think you are crazy but your own sanity is much more important than what other people think. 

P.S. Trust me, nothing is wrong with you. It is all in the mind. Try to control it than let it control you.
