Oh I hate depression so much...I've been struggling with this myself lately. A wise man told me to "separate yourself from the depression". Sometimes Depression is caused by environment, rather than internal conflict. Like a gloomy day can cause depression, or a really bad home situation. When I first went through depression, I more or less gave into it. I clammed up, my only out was the internet and online chatrooms. Now I'm suffering from it again, but due to various circumstances, my usual "outs" are off limits. I've been told to get involved in my work, serve others, just get up and get moving. I know depression is completely against any kind of get up and go attitude, but that is its weakness.
I was also counseled to "focus on the small things". When life gets so big and proportional, sometimes taking it all on at once can cause me to burn out. I'm learning to focus on the immediate "day to day" tasks and duties, and try not to think so much about the bigger stuff. That will come over time
