I am so tired and frustrated. Mom's mobility is limited and she is getting to the point where she cannot get up from a chair. All she seems to want to do is eat junk food and not do her exercises. It's like pulling teeth to get her to do her exercises. Every time that I ask her to do them she says things like "II don't have the energy today, I'll do them tomorrow" or even better "I already did them" when I know that she didn't.
