Hi Wendy,
It sounds like you are having such a hard time right now. I feel for you. I was kind of in the same position five years ago and could not walk five feet to the bathroom from my bed, could not wash my own dishes, or make my bed. I was useless and felt terrible and exhausted with everything I did. But, I had a physical therapist come to my home three times a week and he got me from doing exercises in bed and later up and doing leg lifts on my walker...which I could barely do and would cry afterwards from physical pain and from emotional pain of not being able to do a thing. What I started to do was pray alot and try to do a little bit of something new each week (or sometimes month). THen, I would feel like I accomplished something. It took a long time and five years later I am starting to walk with only one cane now and I can do many more things around the house. I judge my accomplishments on a yearly basis instead of a weekly basis and go from there. Maybe some in-home PT and even done in bed so you don't exhaust yourself would help you out. I even used a book specifically made for exercising in your bed and it really helped. Good luck and I pray you will improve with each day.
Take care,
kathy d
