Can be a very stressful period, any chance you could reduce the stress a little?
Set aside a timetable for studying? Talk to your tutors if you're having difficulties with the work? Get some extended deadlines on work? Surely they can make a few allowances or offer advise on completing projects, their will be other students like yourself up against it with work as well?
Although the hours must be a killer in themselves do you think you could get a slightly easier job?
If you're stressed and flat out and risk of forgetting your meds could your doctor prescribe you something fast acting to take in emergencies. Just a few tablets for just in case.
This is big longshot (!) considering the comitments on your time but do you think you could find more time to do something relaxing or enjoyable to reduce stress?
Don't want to turn you on to another form of self harm but do you think you could loose the baseball bat/give someone else in to lend and remove anything similar. What do you think?
Sorry about all the questions just looking for something that might help, sounds like a very tough time for you.
