I've asked myself the question (why would they like me) and have found that its far easier to tell yourself it doesn't matter. If they really like you, there is a reason for it and questioning it will only make you far less confident. Use this, and you will find a girl that will make you feel like yourself when you're around her. Most people (except narcissists i suppose) lose sight of how they appear to other people. Its a known psychological phenomenon that people assume others around them know more than them. You could think about a similar phenomenon- assuming others are better than you, but the thing is they're most likely thinking the same thing. You've gotta break those lines of thought and just go for it. Life sucks when you can't prove to yourself you're living it.
