A recent article in the Economist explains why comparing to others makes us unhappy. In short, we keep comparing ourselves to people who are better off: http://www.economist.com/news/finance-and-economics/21677223...

That said, I think there are concrete things you could do to improve your current situation. First, it sounds like you now know what to do. That's excellent! At 22, you are not far behind at all.

Early in grad school, things weren't going well and I felt like I was falling behind my peers. I ended up finding a lot of comfort knowing there was a CS professor in my department who had trained as a doctor but then decided his passion was in CS. He basically had to start over in school. To know that one could get a later start and still achieve success was incredibly reassuring.

That said, I think you might also benefit from having a mentor. I have found it useful to have someone experienced and successful from which to learn and model myself after. They have given me the confidence to go and tackle larger problems and helped me move forward when things are looking pretty bleak.
