From my experience depression take all the joy and positive things that we experience in and we tend to ignore them and focus on all the things in our lives we don't like. That may be only my experience though. I try to remind myself that these feelings of despair won't last forever. Being with friends and loved ones help. It may not make the pain go away, but it is nice to know there is still life going on when I just want to crawl up in a ball and hide from the world. I found exercise helps as well. Maybe the body does something after you workout, but I just know I tend to feel better when I work out. There is also therapy. Back when I was really depressed and didn't want to life, I found talking to a psychologist helped me sort out all the emotions that where overwhelming to the point I couldn't cope. Some people find medications very beneficial as well. If you have a doctor you can talk to them about how you are feeling. They can prescribe medications to help with depression. I haven't had any luck with medications, but there are people in this forum that have had much success. I hope this helps.
