Rebelling, in the worst way

I think my body is trying to tell me that it's had enough. That I need to get regular sleep, exercise, and start eating better. I need to stop depending on caffiene to get me through my day and lower my stress level (like that will ever happen). Why now? Why when I only have a few more weeks left in this semester? Why is my insomnia back? I stared at my ceiling for 2 hours last night while trying to sleep. My class schedule is so hectic now that I don't even know if I'm coming or going any more. Save me.
