How long can I take this....

Lately I have just been worn out. So much so that I haven't been doing my job to the best of my ability. I think I am getting burnt out. I want to isolate so bad. Just withdraw from everything. There is nothing quite like not having to talk to anyone. I can go home and go straight to bed without feeling terrible about not spending at least five minutes with my family. How do you handle being burnt out, especially when it feels like there is no way out? I have four months of this constant barage. Working 8 hours during the day plus the hour for every stack of paper I acumulate a day. 2 hours for tests. Then school doesn't just go on at night, but it invades the weekends as well. So I feel like I am stuck in a never ending work week. It's all I can do to get some sleep and food in me. I can't stop working because I have monthly bills to pay. Lately, it seems even crazier because I made a lot of awesome new friends and I want to spend time with them as well. After the sudden loss of my last crew, I feel like I have to spend time with them or they will leave like the others did.

I am stretched so thin I just want to scream. Maybe I just need a good cry. Nothing quite as therapeutic to a female as sweets, a sappy chic flick, and a good cry. How long will that last me? How long can I take this? God if you are reading this..... please, please help me.
