What do I do about my situation? I am upset...?

I just recently changed from a swim club that I have swam for, for three and a half years. I like the new place I am at, but I am feeling very "homesick." I cried last night and tonight because I sort of miss it. I don't know what to do. Did I make a wrong decision or is it just because I have only swam at this place for two days compared to the other place for three years? I am really upset about this. Please help me.
