Hi, I've had the same problem... don't worry! It makes you feel much worse when you don't get a good sleep. There have been many times I just lay in bed and just think. Since then I have gone to therapy, I found thinking about positive things when getting ready for bed helps. My boyfriend is a sweetie and he tries to understand what's going on, but I feel kind of alone sitting in bed tossing and turning. My suggestion is to reach out for therapy... think about the promising future or something or someone that makes you smile before you go to bed. I journaled for a couple weeks when I was very bad off and it helped. I have found that lack of sleep causes an anxiety feeling, you feel behind and never really there. This is why it is important to keep trying! I know I drove my boyfriend insane with my lack of sleep and sleepless nights, but I PROMISE you if you work at it... it will get better and your whole quality of life will improve.
Thanks for posting, glad there are others out there!
