What I regret

I regret a lot of things in life but one of them was being so shy. As kid I had things going on in my life with me losing a house and divorced parents I eventually got over it but still. I was never happy because I wanted things to stay the same. I really regret it because I cause lots of problems I used to cry about everything like everything. Sometimes I just shut myself. It was really hard to explain my feelings to others. My friends used call me emo BUT I wasn't emo just depressed. I also was to shy to stand up for myself. I would always let people walk all over me. But actually I don't really want to go back in time and fix it because I developed over these times and I am more happy and open then I was before. Yes I might be a little bit shy but once I am comfortable I can get out there. Honestly I put the past behind me and let myself just focus on the present. What is something you regret?
