Still tired and depressed

I feel like a zombie today. After work, I passed out for about an hour, woke up starving, and I still feel like I could go to sleep now and wake up in the morning. School has me stressed out. I don't know what is going to happen. I haven't finishes my incompletes and I didn't file a leave of absence and it's been a year. My time is up. Everyone is going to be mad at me. I don't know what's wrong with me. I get so frustrated. When I sit down to do school work, I feel lost and overwhelmed. My knitting has taken over because it helps me get my mind off the reality of the mess I've made. Hubby feels bad, but there's nothing he can do. I really have to fix this.  DH has been wonderful about everything and has offered to come to school with me.
