Some days back I had the same problems.

Do what I did. Go to bad breath deepllllly at list 20-25 time it will help.

Your sleeping problem isn’t from bills or being anxious. It’s the high stress levels you are under from working and going to school while maintaining your grades. Your body is literally thriving on adrenaline because of the stress.
I’ve experienced the same thing working extremely long hours (120 per week) for 2 months. Once the situation settled down (happy client) my body literally caved in. I went home sick and stayed sick for an entire week…my body took that long to recover. You might consider cutting back on the hours you are working so you have time to rest.
If you don’t do something to slow down now you will make yourself very sick.

when your sleep deprived, your body makes ‘emergency’ hormones.. to make you stay awake. it’s possible that your body does not stop itself creating these hormones… i don’t really know. there are also emergency ‘go to sleep’ hormones which can kick in at any time when your not moving alot (which is why it’s dangerous to drive tired) but when i had insomnia aged 15 i didn’t seem to produce these at all.
i put my problem down to being a teenager and now i’m 18 and i’ve pretty much grown out of it. as for your reasons… you could ask your doctor. you could try cutting back on the caffeine and sugar (if your thinking that you can’t do that, then it’s probably the reason).
has it been going on for more than a couple of months? if so, see your doctor. does your brain feel numb? if so, you really need to see your doctor.
it could be a hormonal disorder but it’s most likely a mixture of anxiety and unhealthy diet so try to get people to help you out, keep you calm and relaxed. don’t do any more work than you have to, don’t spend too much money, don’t get too drunk and try to go for that ‘healthy balanced diet’ thing. try lots of red meat – iron is good for insomnia. and 5-a-day fruit and veg. because vitamins help everything.
hope you get better. and hope i helped. and hope you can get away with not having to see the doctor cuz that’s no fun.

Was in your shoes years ago and followed the advies of my doctor, did not use any sleeping aid, and seldom have the problem now.

Sleep is vital to the body, allowing the brain to relax and recover.

The best way to solve sleeping problems is to go to bed at the same time each and every day, and get up at the same time each and every day.

Get off the internet at least one hour before you go to bed. Allow your mind to start winding down. Don’t eat before going to bed except maybe a glass of milk which has enzymes called triptophane that help you relax.

No TV or reading in bed. Bed is for sleeping and sex, nothing else.

NO napping during the day, not cat naps, now power naps. Reteach your body when to go to sleep and when to wake up. From everything I have read, six hours is the minimum need for your body and mind to stay healthy.

your clock probably needs to be reset. your overtired and not getting enough hours. why do you stay up til 2am? you need 8 hours of sleep to be healthy and for your body to function optimally. also take a look at your diet. no caffeine after 6pm and no carbs after dinner. how about medications or supplements? maybe one of them has a side effect of insomnia.
