Hi Richard, no apologies necessary!!!!
you can't help it. just keep busy and stay in the rhythm: wake up early and go to bed on time.
walking helps, and how funny this may sound, singing helps to. (it clears your head.)
I've had it to, for me the scroll saw was a way to get back on track. (had to use medicine to for more then a year)
I know the feeling that you hang in the background (not just on this forum I guess)
no problems there. just read and try to enjoy.
you just made the first step and we're all here to support you!
