How can I get over being homesick?

This is my second week away from home at college. Everyone is really nice here, and I have some friends, but I am really homesick. I wake up every morning worried about the day and sad that I’m here. It’s really hard and I don’t know how to get over it. I go out and do things with people but as soon as I leave them, the feeling comes right back. I just feel so overwhelmed and it seems like everyone else is just having an amazing time. I’m not and I’m not sure what to do about it. I find myself on the verge of tears pretty much every day and it is so hard to make myself get out there and do things with people that I don’t necessarily like/know well yet. I can’t imagine that they will ever make me feel as safe and loved as my family does. Any ideas? Any similar experiences? I hope I’m not the only person in the history of the world who misses being home after a few weeks—because that’s sure what it seems like here.
