I've felt like that. Not wanting to do much and isolating my self. Thinking I'm not worth much. Not wanting to say much when I'm around other people. Feeling slowed down. Yea, depression sucks and it's hard to get out of. I was depressed for the last 5 months. What kept me going was finding things to do to keep my mind busy. It can be walking a dog, taking a shower, watching some TV shows, playing a video game, going to work, starting up a hobby, or getting together with friends (they can be very supportive). Best advice is to try and stay active. I finally came out of my depression and it's a world of difference. Good luck to you, hope you come out of it and feel relieved.
