I tried some stretchy braces for my knees which helped enough to get out and walk. To walk in nature as often as I can has helped with the depression. When I was feeling particularly low (pain and lack of sleep will do that) I would place my hand on my heart when I woke up and tell myself that I was a beautiful person and it is a great day to be alive. Even a fake smile helps to bring some joy to your heart. Hand in there my fellow warrior. We’ve got this!
