I know that my depression is inherited. I found a wonderful combination of drugs that do help me so very much to be able to stop the sliding into a dark space. I know I'll be on drugs the rest of my life, but it they keep me balanced and able to just enjoy life - so? I'm pretty sure that depression is linked to a few things, but my bet is that they are neurological in nature, and not hearing loss on the side. 🙂
