What's Wrong with me

I wish I knew what is going on with me right now. At times, I can get frustrated so easily to where if I don't tell myself to calm down I'll probably end up snapping someone's head off verbally. My friends haven't really been that much help to me in asking me what is going on when I need them now more than ever. I also feel so overwhelmed even though I am only taking sixteen credit hours. I also need to raise $2,100 to go a missions trip to Azerbijan for a may term. After I found out that a friend of mine that lived on campus here has now moved to Clemson without even saying to goodbye to anyone as well. I shouldn't feel this frustrated with it only being the start of the semester, but sometimes I just can't help it.
