A Friendless Summer???

Im currently in the midst of my summer vacation before I start my senior year of H.S, and Im dying of absolute boredom. I only have a few friends in school, but they are all busy either on vacation or at camps and are never able to hang out, leaving me with nothing to do. Ive finished my summer reading and so many other books, that Ive gotten sick of reading. My parent tell me to study for the ACT, which Ive been doing occasionally, but I don't think its fair that I have to spend my last high school vacation (because next summer ill be getting ready for college) doing nothing. I already volunteer at the local hospital a few days a week, and have hobbies, which leaves me nothing to do. Im also sick of playing xbox and watching tv. Both my brother and sister are ALWAYS out, leaving me alone. I can't go on vacation either because my parents have to work. I honestly don't know what to do with my life.
