A couple years back, I was in a big mess. It was an emotional nightmare. I would get panicked about going out in public, and was eventually diagnosed with clinical depression.
I can tell you that it w one of the biggest messes of my life and it was only by the grace of God that I was able to deal with it.
There is no cleaning up clinical depression, no ten step process, no sure fire cure. It's more of a treatment. You find things that help you function. I personally was helped by the medical profession and the use of prescription medications. I won't cured by them and when I came off of them, I wondered how the benefit could ever outweigh the cost of what occurs during detox, but they did help me to function and survive.
My best advice to you if you find yourself in the midst of depression is to find someone that you can talk to. Cry out to God, he is always present to hear us. And cry out to your neighbors, friends and family. Don't suffer in the midst of the darkness alone. One of the things that I heard over and over again when I started telling people that I was depressed was "You?! You're depressed? I would have never known." It's amazing how much a shower and clean clothes can hid from those around you.
I could probably write about this all day, but I won't. Just want to remind you that if you find yourself in the midst of an emotional mess, it's okay to get help.
