I don't believe the depression can be destroyed !
I watched my mom live with it, She died from cancer in 1994. Three of my four kids Zach, Ryan ,and Jillian deal with it sometimes at least monthly. I have been fighting this thing as long as i can remember.
All of us have had multiple visits to the mental health clinics. We renamed them the "Doyle Institue Of Higher learning".
I Have spent 32 days in four different institutions since mid December 07 this June 6. I am not sure why, it stays with me daily.
The only thing that keeps me going is GOD and my kids.
