anxiety
"I am told I am a reasonably intelligent 64 yo. In all honesty my Mother is probably a little biased.  
I have suffered and I do mean suffered severe bouts of anxiety and debilitating depression for over 50 years. As you might Imagine I have seen everybody, tried every remedy under God's sun. 

Drug companies in this and most other countries are motivated by one thing ONLY. Greed/MONEY and getting more. If someone can be helped as a side effect along the way, it makes great press but it sure isn't essential. 

I found a Loooooong time ago that I had to do the research into my own personal condition, that I had to in essence, become my own Doctor."
