I know, for me, nights are the hardest time. It seems like the darkness unleashes my "demons" for some reason. The worst is when I can't sleep, I start thinking all kinds for crazy stuff. It used to be every night, but now it's only occassionally. Glad to hear you are feeling better this morning.
When I can't sleep, I now try to do anything to keep my mind from wandering to those dark places. Sometimes I will even get up, walk around, anything to shake those thoughts. Usually when I find myself going there I will "force" myself to think about something else, something more positive. One of my favorites it to think about what I'd do if I had unlimited money. All the people I could help, all the nice stuff I'd buy, the places I'd go visit. Its a bit narcisic, but at least it's a positive obsession!!
Hope you sleep better tonight. Take care.
