Why do people dislike me so much?

Is it possible you talk too much?  I have this friend who is a truely wonderful, good hearted person, but she talks too much, monopolizes the conversation, and MUMBLES!  It's very annoying. 

I'd suggest seeking counseling with such an issue. They can get into the details and help you sort out your perceptions and realities. All too often, what we THINK we see isn't quite the reality we think it is. 

There are all kinds of people in the world which you would meet, not everybody may like you, at times it also happens as majority dont like you, but dont get disheartened try focussing on your life and dont bother, I am sure you will find friends for yourself.
