Why do craptastical things keep happening?

I'm sitting at my campus job, and my boss from my theatre calls me and asks "can you put in your 2 weeks notice so we can promote your sister?"... Damn it. I mean, I'm happy for her and everything, but I really love that job. I don't want to quit, and I don't want to transfer theatres, because I really love the people at my theatre. I understand that I'm not there for most of the year, but still, I don't want to stop working there. I guess it won't affect me if I can get the job I have been going for up here. But i'll still miss it.
Some more craptastical stuff that has devoloped recently:
I feel like I'm drifting farther and farther apart from one of my best friends. We were fine the first semester she was here, and now she barely ever talks to me. I feel like i'm an after thought in her head if I am even lucky enough to be there. It really hurts. I ask her if I did something, and the answer is always no, but I can't help feeling like I am being forgoten and replaced. I try to communicate and it's always the same. Either no, or plans, or other friends. Go ahead and make other friends, but don't forget about me too. The person who stood by you when others wouldn't. Who comforted you when you needed it. Who loves you like a sister.

I'm going to go sulk now.
