Having struggled with depression a long time, I too feel numb and just don't care. I am sure the depression is causing me to feel this way. Several weeks ago I had a depression-free day - the first in years. I wasn't ruminating with all the negative thoughts that I usually have. That convinces me that there is a chemical inbalance. So I'm going to a new pdoc, hoping for the right med(s). Don't let depression win, try something else (new med).
