What is the problem?
Why do you feel like a failure?
Why do you want to give up?
I have had many of those days but it usually turns around, and there is no point in giving up, fight for what you want, that's half the battle and a challenge is fun right?
It's hard to know what you are going through as you have not said but you sound very depressed, possibly feeling alone and rejected, would I be right in this way of thinking? (I am just going on how it's been for me in the past when I have talked like you have being in this post).
Don't give in, ever! Your likely to get more help if people know you are trying as well. It will get better life has it's up days and it's down days which I can tell you are having a very down day right now.
Also not to sound mean but why not you? why should anyone else have to experience this? Why should anyone?! I know it isnt nice but things can happen to anyone, no particular reason why they just do! Just got to try handle them the best you can
