Dread to go to sleep

Isn't sleeping supposed to be the time when we relax and finish off the day? when we close our eyes and leave the day behind to go into lala land? Sometimes i really hate my insomnia and curse it but then i can't help it and i try to think everybody has some issues and there are many insomniacs out there not just me , this relieves me a little but still...i wish they would finally invite the non addictive none REM sleep disturbing , no tolerance building magic pill for people like us, because when its sleeping time i wanna feel relaxed like i should not to dread and be anxious if its gonna be another sleepless night.
