For me, a few months of good eating, vitamins, sunshine, and walks really helped me get back to some sort of ability to decide whether I needed to see someone about getting medication. In my case, I wasn't as depressed as I initially thought. I was just coming off chemicals and my brain needed time to adjust.
In the meantime along with the activities above, I went to lots of AA meetings and that helped me immensely....most alkies/druggies struggle with depression, anxiety, bipolar, etc and it was nice to not be isolated in my head. Bad place to be without adult supervision.
