I believe our brains can adapt. Depression can be treated, and so can anxiety over it. Keep thinking in a good way and not obsess over what may or may not happen. If my brain got smaller over the depression in my life, right now mine would be the size of a peanut!!!!!! I get help from my doctor, and take some medications for it. To me that is the best answer. Talk to your doctor Matt, and see if you can get some more help. I do care. ginnie
