Yes, I understand. Go out in nature and spend some time there. I went this morning to a lake/forest/lots of green trees. I went there with my husband and we just sat and listened. Approx 45 minutes of soaking in that silence. I like to knit on the bench but this time I sat like an amoeba. No thinking, no doing...just being in a sort of vegetative state.
It was wonderful, more helpful than a pill or other treatment. I'm serious here. People were fishing on the lake, children were playing with the dogs, birds were singing and so on ... so it was not deep silence but for me...it was a mental treatment.
Mother Nature is so soothing...
On the other hand, I'm going to start an exercise routine lifting weights. I'm in a sad bad shape physically. And I used to be a gymnast in great shape. Only in the last few years since Corona I got gradually more and more sedentary. Of course the pain increased. I have to push myself to do this type of exercise. I started many times and after once a week (one session/week) I gave up. I like to walk outside but I need a more serious type of physical activity.
I'm 55 and I'll be 60 in a few years and I don't want to be stiff and in pain, I detest feeling less than optimal. It stresses me out.
I think you can start some form of exercise and you'll certainly benefit from it. Mentally I mean. And physically as well. It's a stress reliever for sure. The hard thing is to start. I know...I'm rather lazy, I admit it. But I always feel better after my workouts. I never regretted working out. Never.
Take care.
