Looking for answers, but they seem to keep changing

I have recently noticed that I second guess myself a lot. It's not just with questions on tests, I do that too, but it's more than that. School is starting to really stress me out, and I keep thinking that maybe this isn't the right place for me right now. I don't know what put that idea in my head, because I started out loving it here. It was wonderful, I loved my friends, my classes were bearable, and being here was actually fun. Recently though, I've realized how much my friends and friendships with people have changed, my classes still are tolerable, but I find myself aching to go home. It's possible that I've been home too recently, I was home three weekends in a row because of watching my siblings while my parents were in D.C. and spring break. I stayed this weekend because I had a busy day yesterday. It wasn't really a bad weekend, because a few of my friends stayed, it was just extremely boring. When I'm bored, I think, listen to music, or watch tv. All three are dangerous. I think about stuff like where my life is headed, what God wants to do with me, and what i'm doing at a small school majoring in accounting of all things. I think about how different this summer will be like since I won't be swimming, which has been part of my summers since I was 4. I don't think I realized how much I would miss it. I also think about how I don't yet know what I'm going to be doing this summer. My SummerShine application stares at me every time I turn on my computer, but for some reason I can't finish filling it out. Every time I open it up to finish, I find myself distracted, or I can't find the words that I want to say. I should have already sent it in, but I can only wonder whether it's the right choice for me this summer. When I listen to music, I almost always come across a song that reminds me of my wonderful friends at home, and it makes me want to cry, because I miss them so much. When I watch tv, I always seem to stumble across stressful wedding shows like Suprise Wedding, that make it hard to sleep (You can't fully understand why unless you've seen it). I miss my friends and my family, and I'm considering going home next weekend, even though I know that it will only make it worse. I'm so ready for summer...but then again I'm not, because it's just not going to be the same.
