school is killing me....

I'm losing my mind. I'm drowning in school and it's making me miserable. I'm trying so hard to get good grades but I can't balance four hard college courses plus being a wife and a healthy human. I don't know what to do. I'm sitting here trying to write a research paper that is due in 12 hours. I have 1/6 pages down and I can't do it. I can't figure out what the hell the teacher wants and I'm losing my mind. I want to just stop and go to bed. I can feel a panic attack creeping up on me and I don't know what to do. teaches don't take mental health into consideration when grading. also I'm almost 6 weeks pregnant and I'm stressing about what the stress could do to my tiny tiny baby. what am I supposed to do?
