Hello, Suzi! I'm sure many folks will like talking with you! I'm so sorry about all the things you are going through. You must be a very strong woman to be doing so much under the circumstances, and I applaud you!
The main thing I would suggest, and of course I'm just a person like you, is that you not make your path too hard. Gosh, it's already hard enough! I think the walking is a great thing for you to do. And be sure that you eat healthy, nutritious foods--stay away from the "fast foods," they are loaded with calories that no one needs. Vegetables, complex carbohydrates like whole grains, and good protein--make sure you get enough protein. But take it easy--don't make it just one more terrible chore that you have to do!
We'll be rooting for you here--check back often. Look around at all the other forums as well.
