Can’t sleep

hey, so i have found it lately really hard to fall asleep. bc i have a fear of getting charlie horses. i know it’s nothing to be in full fear of but they are really bad for me bc i don’t handle pain well. my mom says i should take melatonin, bc it will help me go to sleep and that its a natural thing that my brain already releases into my system. but for some reason taking something to help me sleep makes me feel unsteady. i also have bad anxiety and so that doesnt help either. so if anyone has any suggestions i am all open to ideas and stuff like that. bc i really need to figure out something, bc i go to college in the fall and i won’t have my mom close by so i just need some help bc i don’t know what else to do. thanks guys!!!
