The past follows you everywhere

I thought I am over the years I was bullyed by the girls in my class. But yesterday I was watching a movie with that Topic and at the end I was crying. It was a sad movie but not that sad, that it is a reason to break down in cry like I did.
I realized once again, that I have still problems, which I just push away and ignore. So that I don't need to deal with them.
In generall that is nothing bad. But there should be one time when you take your time for it and deal with it. I think I need to come over some of my Problems and "close" them.
Till now I don't really have an Idea how to make it.
I'll see.
