Hello Sundra Ann:
Welcome to the boards...
Goodness, you deserve a gold medal for caring for your mother for ten years. It is no wonder that you have such feelings - you are surely overwhelmed with a bed-bound mom. You do need help in such a situation.
I wonder what are some of the details of your mother's health and such? I know care-giver companies can be expensive but many do have some sort of nursing staff. Does she have a doctor that can assist you with some sort of care giving plan? It might be worth a call and see what the doctor may say. There also may be resources available through the local senior programs or through the local churches that the doctor could refer you to.
Meanwhile, take a deep breath and exhale. Listen to some music or walk outside and listen to the birds chirp for a little while. Open up to the love in the universe and know you are not alone.
