Sorry to hear about your grandmother and in the past I’ve read about when someone is worried and can’t sleep they write down the problems or worries. Then with worries written down it helps them be go sleep or in theory it does anyway. I’m tired tonight and slept poorly last night due to inadequate sleep since need 7-8 hours and slept maybe 4-5 hrs. Sometimes it’s a lack of discipline and I need to make myself just get to bed on time and other times I get to bed, but lay there and the last thing I can do is fall asleep.
