Prayer Request

The last few weeks I've been battling though some strange emotions. I feel really tired and it doesn't take much to make me cry. I'm really not sure what's going on! And it's not like I'm constantly depressed or anything, but once I start, I'll be in the mode all day. It's really affecting my relationships and my homework now. It's not fair that everyone else has to deal with my instability. So, could you please pray that God will make it clear just what is causing all of this? And that He would help me work through it. Praise Him for providing caring people along the way to help me out.
