What are some ways to release my bottled up emotions?

I like to bottle up my emotions. I think its come to a point where I am really bad at communicating my emotions. My parents are divorced and I just absolutely hate my dad and stepmom. Ive tried talking to them but they dont listen. I do vent to my friends on occasion, which helps a little, but isnt really enough. What are some outlets or like hobbies I could do to release these emotions? Im really artsy. I dont like writing in a jornal. So if that helps at all. please help?
