Hi I'm sorry to hear this.. this is not a commercial it's my own experience because I wanted just to stop working last year I couldn't do it due to musclepain whole day long. After watching the video I ordered a half sheet to try out at www.aarding.org the American site is https://www.earthing.com/collections/all-products/
My life turned a bit more bearable if I stop working i lose my home so I need to stay working. It doesn't solve the problem but for my muscle problem and pain at night and morning it was a day night difference. Of course it falls back sometimes if I do too much but it really is helping me. I don't say it will help you. It isn't psychological because one day I thought it doesn't work anymore I was back at the beginning as I saw later the cable was loose in my bathroom. After fastening the earthcable it was working again.
Stay strong. Believe in yourself that's the only thing you have. Try to do some positive things like watch a funny show in tv. I hope you feel better soon.
