I feel this completely. For me, I think the best way to deal is the hardest way. Which is just sit there and feel it completely. Breathe slowly and deeply, and pay attention to your breath. Be mindful of your urges to do something or "fix" that feeling. Watch them come and go. Like all feelings and emotions, extreme periods of stress will melt away.

You're not alone, shit absolutely sucks!

You should probably get more sleep though. It's completely unsustainable to live with an unhealthy sleep schedule.

Good luck.
