affect effect

I'm affected by a few things that i think others are thinking of me ( not just on one matter..). ... Am i affected because what they say are wrong? Or am i affected because what they say are right? ... I think it's the latter because i'm feeling kind of guilty. I deserve to feel like this.. :s From now on, I shouldn't.. must not commit any mistakes that will lead me down to these paths again.. I'll really try... I'm sorry.
