Dealing with mental problems, working and going to school can be tough. I cut back on my work ours which has helped some. But, I have no advice that you probably haven't heard already. If you have been struggling with this for years, you should probably be giving me the tips because I have never experienced major depression ( unless this so called adjustment disorder is really just plain old depression which I think it might be).
So, I will just say what you have probably heard many times. You sound like you are working on an important goal in your life-pharmacy. I tend to plan ahead on the days that my planning compacity is on-line to compensate for the days when my ability to think about the future is non-existant. This trick helps me to get my homework done on time. I tend to break my school tasks and home assignments down to make them feel more acheivable. I tend to get bogged down by my tendency to drowned in negative thinking/loss of hope (long history of negative thinking-Dysthymic Disorder). I wish I could say that I have succeeded so you can. But, I can't say that. I can only say that we are all on the same journey of self-improvement. May you have good fortune on your journey to a better you.
