sleep aid help please!!!!

Jayce
I work at night and go to school, on top of that I was pre medically diagnosed with insomnia but didn't have the health coverage to keep going to a doctor. I can't sleep and because of it I can't eat. With that said, it's throwing my hormones out of whack making my cycle an endless rollercoaster. Please any ideas would be helpful! I have tried hot showers at night, melatonin, sleepy time team. None of it is working
