>>1 don't worry, you just found out the truth about life. Like >>2 said you can lie to yourself professionaly with therapy or numb yourself by taking anti-depressants. Or which MANY people do, just ignore your feelings and do random boring stuff like going to work 5 days a week, that way you are too busy to think about the pain of life, that's why many say it's important to have a job.

Goodluck! (you are the only who can decide if your life is worth living, no one..no one can know the pain of living it, onl you.)
