Its killing me. Its been like this for months. Usually awake from 4-5 but sometimes its 3-5. I have to get up for work 6am ish. It makes no difference how tired I am. Ive had it before in the past. I know that it is linked to depression but dont know why (like the doctor bothers telling you)

Will it affect me long term? Age me, affect my body? Does anybody have the same and how do you cope?
