I find it helpful to make sure there is SOME slack in my schedule so that I can cut back if need be. I am going to school full time right now as well as working part time - 8 hours a week. However, my classes are only three days a week with the rest of the time meant for studying/doing HW, so there is a bit of leeway there in terms of when my school work gets done and how much else gets done. I try to do as much as I can in terms of housework etc., but if I am too tired, that has to be the thing I cut down on (a messy house just can't be my priority right now). I try make sure I get enough sleep and take care of myself first, because if I don't I know I'll burn out and end up with a problem.

Can you start slow, like take one or two classes or work one or two days a week, to see how that goes? That way you can increase or decrease from there as needed?

Good luck to you - I know it isn't easy!
