Hi Earl! I am sorry that your DW is not happy with her job and having trouble. I think most people are not happy in their jobs and it is all too sad. We spend more waking hours a day at our jobs than at home.
Has she looked in to State Vocational Rehabilitation? She may qualify for it and apparently it is an awesome program - highly recommended by many I know in the rehab field as well as some physicians. They have you do all sorts of tests - interest inventory, vocational evaluation, etc. to see what types of positions would best suit you. They will pay for her retraining and work with Disabled Student Services at the retraining facility that she chooses to go to.
I wish her the best and let us know how she is doing.
