Hi stress, anxiety, sleeplessness I’m sure alot of people can say some of this is part of the challenge of separation. Health Issues as well can come up too, I found a number of things have helped, for sure social interaction, friends and change of environment really help everyone who’s at home alone with their problems and children who are too young to really talk about things. I found cutting out tea and coffee was a big help, yes mega tired for a while, that helped me sleep more, then waking up in the middle of the night was a problem. My solution is chamomile tea before sleep, and Valerian root Holland and Barrett do capsules. I also cut out as much sweets as I can manage as this seemed to cause anxiety when blood sugar peaked and dropped, walking during the day also helps. It would be great to hear other peoples strategies that helped. I wish you well
