I'm having trouble sleeping this isn't the first time, had trouble in high school, but now it's happening again. is there anything i can get or do?

Insomnia : Is relatively common. Needs full assessment as occasionally there can be underlying physical or mental health factors. This can then allow your doctor to work out options in terms of treatment - although these can be difficult too

Sleep hygiene: This is a simple concept. Make it the most optimal circumstance to get to sleep. Exercise regularly, morning may be best. Low sugar and caffeine intake and not later in the day. Earlier dinner and avoid stress if possible at night. When you are ready to go to bed read or watch TV but not in bed. Only get into bed when you are ready to sleep. There are other things like white noise machines.
