Whilst I am really happy that you found your solution, it's akin to most people telling a depressed person to 'find something that you enjoy'. When you don't enjoy anything - or the things that do bring you comfort are bad and/or isolating - you are stuck.
I experienced depression for many years. Perhaps the worst part of depression, and what makes it so hard to treat, is this defeatist attitude of "nothing is going to work, so I may as well not try".
Start by accepting that other people in your exact same circumstances, with your exact same abilities, go through life with a smile on their faces. Ask yourself, what is different about them? That is how I started to crawl out of the hole.
