Because of some personal reasoning I have suffered from moderate anxiety for 6 months and after that 3 years of mild anxiety when I was a teen (from age 15 to 19). After the anxiety I lived happily for 7 years but after 7 years I have again suffer 2 months of moderate and 10 months of mild anxiety because of some reasons. 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. Please tell me is it possible that after nearly 5 years of anxiety my brain didn't shrinked if yes then why it didn't shrinked.
