You have to make the difference. Whatever is bothering you or praying on your mind, you need to confront it. If it is job worries you need to work harder or increase your education. If it is relationship worries you need to get out there, go to more social events, join a club. If it's money worries you need to budget and be disciplined.
If it someone wants to kick your ass you need to confront them, get the kicking out the way or beat them up, after it's over, it's over.
If you cannot find the motivation to confront it, apart from the fact you're a loser and you need a kick in the arse, talking helps.
