Google - I feel like a really bad person my gifriend loves me or says so I have friends but I still?

It's hard, when some things we're good at or that are positive qualities, and other things we suck at or are negative qualities. We can choose which to focus on, and how we decide to view ourselves. I see no benefit in looking down on oneself, except for short periods of introspection, to see where you can improve. I see much more benefit in focusing on what's good about you. It will help build confidence, and with confidence comes the courage to take on new challenges.
