Life isn't fair at all. No one promised you it would. Others also have their problems that could be much more serious than yours. Or they may not, that's life. You think people with disabilities or victims of terrorism etc. deserved their fate, their life path? Of course they didn't, and you did not. The first thing you should do is stop blaming everyone and everything in your own problems, you hold a grudge against others for being able to do what you can't. Secondy, you have to accept your inferiority. Don't pay too much attention to it, believe me, it will come with time. All the best.
