Sleep Issues?

My boyfriend can never sleep. He might be able to sleep once or twice a week. I’ve tried to do as much research as possible to try and help him but no matter what nothing new or helpful pops up. He doesn’t like going to the doctor or asking for help from others so I’m doing it for him haha

Anyway, he said that within the last three days, he got one hour of sleep total. Most of the time when he’s laying in bed trying to sleep, he just feels himself perfectly awake in bed with his eyes closed for the entire night. I feel so bad and I just want to help him in any way I can. He said sleeps better with my presence or scent of either myself or my perfume, but even then it’s such a dilemma/process to fall asleep and he almost never does anyway. It’s even harder considering we don’t and can’t live together too, so even if I help him sleep the most I can do is be on the phone with him at night and spray my perfume on a pillow or something in his room. Does anyone possibly know if he has a sleeping disorder, or any possible reason why my boyfriend can’t sleep? Any info would be appreciated!!
