Past frustrated

I don't know what the word I should use is, but I have past frustrated. My walking has gotten so bad that I can barely make it 3 feet at therapy when I used to be able to make it fine across the gym. I can only walk with hubby leading me now. We are back to working on just standing. I even had trouble today transferring from my wheel chair to the therapy table. That is something I have done easily for months. Ugh. I should have stayed under the covers today.
