Hi RJ ,
Hope you are ok today.
I have found myself ruminating late at night with the 'what if's and buts etc of life.I got myself into a right state just last week with it all and spent a week in a respite center as I could not cope anymore. The worst times of the day for me are , first thing in the morning, and when I go to bed.
Try somehow to distract yourself to relax your mood. Depending how I feel something as simple as going for a walk or for me, having a bath before I get into bed works, as it relaxes you. Don't drink to many brews as i have found it keeps you awake , well it does me anyway. I usually try to find something relaxing to watch on telly before i sleep, some prefer reading as a way to relax. You may have tried alsorts but we are here to support each other.
