Home for the summer and miserable. Any ideas?

College just got out and I am home for a whopping 3 months. I should be happy, but I am terribly depressed. The first thing my dad started doing when I got home was yelling at me and reminding me of all the house rules. I miss my friends at college, most of the people here that I used to hang out with in high school are all into hard drugs (cocaine and heroin) so I don't want to hang around them. It has also made me start missing my ex-boyfriend since I have basically no friends here or anything to do. Any ideas on how to make my summer better/go by faster?
