Now that the new year 2015 has passed... Do you have any regrets?

I have a lot of regrets from 2015 and I had them actually before the New Year started. I think my biggest regrets was my attitude last year. I was having a very tough year and things just kept getting worse and worse and so I lashed out on a lot of people. Toward the end of the year in November, I started getting people out of my life completely. Dropping people who were toxic for me and blocking them, then I began making new friends who were much more positive.
