I don't know

I can't help but look at the past, and see all the terrible things I have gone through. I didn't think I had it that hard, but I did. I spent all this time disagreeing with the facts, but they are all there. I have been crucially been bullied since I was in fifth grade, age 10. That is four years of bullying. I didn't think about all the shit done to me, until now. It is all so much, when I think of everything at once.  It is so overwhelming, and I don't know where to put all of this emotion. I just feel like i'm about to fucking explode, with all these problems, and feelings. It is way to much to handle, I need to let it all out, advice?
