Concerns About Insomnia and Memory After Treatments - #50561

I have taken lot of allopathic medicines as well as rtms treatment. And ever since rtms treatment, I started getting bouts of insomnia.Then on regular medicines for ocd/anxiety, I was okay but gained a lot of weight. On stopping, I had severe symptoms of withdrawal that I went sleepless for months and other physical symptoms plus weight loss and severe insomnia. I had to restart treatment under another doctor but this got delayed by a year. Then with alternative treatments and allopathy, I could sleep a bit. 5+ years, sleep has been very very less. < 4 hours. Memory issues and concentration issues that were never there earlier. Has there been any harm due to excess cortisol for long periods of time in the brain and body? I started ayurvedic treatment and so far I have taken the following arisha, kashyam meds and now manasmitra and bhrami and mahakalyanak grith. On taking Brahmidrakshyadi kashyam, I think I got side effects but I am not sure. Will my brain and body ever recover? how long will it take for my memoryto return to normal, if at all? will I get completely alright or there may have been loss of brain cells due to chemical and hormonal imbalances? please guide correctly.
