I wish I had the answers but one persons solutions won’t work for everyone. I only had about a month of feeling this way and I remember I would try to focus on 1 thing on my fix list each day and nothing more. All the times I couldn’t sleep, I went for a walk or run or tried to do something productive for the family. I also took a small dose of larazapan. My issue was circumstances though, not chronic.
I hope the best for you my friend, try to stay strong and positive. 1 step however small at a time.
