I think I'm going crazy!

This week has seemed like quite an odd week. I feel like I'm going crazy, all week I have felt very discombobulated, my thoughts are scrambled, I feel one step forward at times and at others three steps back, I don't have a ton of homework so I feel like I'm forgetting assignments, I keep misplacing and losing things and all this week the days just don't feel right. This week Monday felt like it was Wednesday, Tuesday felt like Thursday, Wednesday I couldn't decide at all; one moment it felt like Sunday,  another moment it felt like Monday, and at other times it felt like Friday; and today it feels like it should be a Sunday. All this confusion and I cant figure out why. I'm just very out of it. I really hope that I can get my head on straight before next week comes around because I'm not sure if I can keep from going insane if I have to go through this another week.
