Because of some personal reasons I have suffered from 5 years of anxiety when I was a teen (from age 15 to 19) and recovered without any medicines. After the anxiety I lived happily for 7 years but after 7 years I have again suffered from 1.5 years of anxiety because of some reasons and again recovered without any medicines. So it was total of 6.5 years of anxiety I suffered. I am not sure about the severity of the anxiety because I don't know how much is severe in case of anxiety. Now I am fine but I have heard constant anxiety causes hippocampus to shrink and now I am worried about my brain that does It has shrinked. I feel my memory and other functions are normal but I am not 100% sure about it. Because I think little bit of shrinkage will not reflect on my memory that much which can be noticed by myself. Please tell me is it possible that after nearly 6.5 years of anxiety my brain didn't shrinked if yes then why it didn't shrinked. And how much time Anxiety or other mental problems like depression takes to shrink the hippocampus. And is the shrinkage permanent or reversible. And if it reversible how can we reverse it.
