Can't sleep.

It's almost 5 am and I have been tossing and turning all night, unable to get some sleep. I don't have anything to be losing sleep over. The past week has been alright aside from the fact that my dad's surgery was cancelled. Luckily he's going in on his birthday (Yee haw, right?) to get his leg fixed. As for me, I feel like there is something going on with me lately. I'll have great days, but then some days things just won't seem to go right, no matter how hard I want them to. I don't really know what I'm talking about, because I can't pinpoint what the heck is wrong with me. I will feel really down about myself and then get really upset about it for no reason. I'm not eating healthy, and I'll eat anything bad that I can get my hands on. I don't know of any situation that should be sparking any of this. I just need to forget about it and buck up. Sorry, just needed to get this off my shoulders, whatever this may be.
