Stressed my head off.

I am super stressed out about school right now. I feel like I have way too much going on in that area but actually I only have like few larger projects to get done. Next week is an exam week, more to stress about I guess. I don't know what has happened to me over the last year. I used to study a hell of a lot and did everything in time. I did stress about everything then too, but now I'm leaving everything until the last minute and trying to find someone to blame. It is me myself who to blame. I am the one doing it or leaving it undone.  I just have to deal with it. I have literally lost my motivation and determination. Don't know what to do anymore.
