I don't know what to do. I've been in a funk lately. I started getting 4 to 5 hours of sleep a night because of school. Normally if I do that every few days, I can cope just fine, but lately it is taking a toll on me. Now when I actually have time to sleep, my body just wakes me up whenever it feels like it. I feel emptier than usual. I'm normally always happy, always motivated, but I feel like something is missing. I want to get back to where I once was, but I don't know how. And I really want to stay away from sleep medication, for I fear it will only mess me up more. What do I do?
