Confidence?

Some might say I am a great listener and I pride myself with that, I help other with their problems or if they are in dark times.Although I feel this way, sometimes I'm not confident about many aspects of my life, in fact it is a struggle to find confidence within myself most times. Others have confidence in me though, they talk about my arts, and my smarts,but I feel like it's just a thing I do, it's not special;I'm not special. I think overall I just need a self confidence boost. What I could do to fake it until I become it is just smiling through my self doubt, putting a happy bag over my head and staying positive. As well as continuing to help others with their problems, and try not to develop new ones.
