You are not alone at all in how you feel. Depression has a way of sucking the fun and enjoyment out of pretty much everything. I can also relate to what you say about video games - I play way too much video games - but I play so much because I find I can forget about the depression. I can forget about the stress, anxiety, and sadness and lose myself in the game - focusing on nothing but the next task. Please don't feel you are alone in what you are going through.
