I Am A 38 Yr Old Stay At Home Mom.

I am a 38 yr old stay at home mom. I have been locked in my house sleeping at night & laying all day on the couch in my living room, for over 7yrs. I was in a bad car accident 7yrs ago & had surgery on my foot & couldn't stand-was on a Walker for 9months, that had me stuck on the couch cuz the Walker wouldn't fit in my bedroom door. I know it's depression. I haven't seen my family in yrs, speak rarely. I haven't found much happiness in anything in a very long time. I do the very minimium to get thru the day. I try to hide my laziness. I have gained over 50lbs & very ashamed. I procastinate everything, my memory is gone. I'm not sure if it's selective memory, but I can't remember things I need to do, have to keep a notebook & write everything down. I know I need physiological help, but can't bring myself to make an apt. I have many things I want to do, but don't do anything!
