It is good to find an activity which allows you to express yourself. There's something liberating about letting your hair down whether it's on a dance floor, writing your thoughts down (like I am right now) or singing in a shower.
We often have so many suppressed thoughts, desires or angst which have nowhere to go, no outlet. You could hit the gym, listen to music or lose yourself in an artistic endeavour. Just find something that helps you find your release. Oh, and I know it's easier said than done but it also helps to not take ourselves so seriously. This is what I learn from being around my non judgemental pugs. It's okay to be really silly ;)
