Hi Holly,
I'm not sure how to spark your Moms interest. We live in the U.P. and I said as soon as it warms up I'm walking the board walk and my husband reminds me of that alot. When you have been laid up for a long time its hard to get motivated so I know if she starts to do an activity as part of a schedule that might help. But I think she will need you to really help her along, do you think she might be depressed ? I feel bad for you it sounds like you are working so hard for your Mom and that's not easy. Our oldest is 26 and I cant even imagine if it were her in that spot. We have a daughter that lives in Ann Arbor and she felt so guilty leaving to go back after spending 3 months here at home helping with her Dad.
Do you belong to a church? Sometimes there are groups that she could join there. Well I don't think I helped too much, I do want you to know you aren't alone and if I think of any thing I will drop you a line.
Take care of yourself and try to take time for yourself,
Dawn:)
