For sleep get some Melatonin. When I was up at night with my mind racing it would put me into a deep sleep. It's not a depressant and is natural so I would take 5 or 6 tabs. Sleep definitely helps. Eat healthily. Fruits & veggies. \
I also found a couple of glasses of wine before bed helped too, but you have to be careful it doesn't become a habit. Use with caution.
