My lifes taken a turn for the worst and i feel like i will be single forever...? Does this happen i'm 19?

Wow you think you have problems!? Try not getting invited to any parties and not hooking up with ANY girls ever.. Try not getting asked out by ANY girls.. Yes you are too picky if you've been asked out by 13 girls and rejected them all. Yes you are too picky if you find something wrong with all the girls you've liked in the past. Try dating one of the girls you've hooked up with or the most eligible girl who's ever asked you out. You have no real reason to complain or feel depressed.
