First if it were me, I would take a deep breath and cut yourself a break. You are a wifeand mother and you definately have your hands full. Sometimes as a caregiver we don't get enough praise when we do something kind for our loved one. I can tell you it is the hardest job you will ever do! I wish I had a magic word or could make you feel better. I think anyone who cares for a loved one needs love returned. Remember you are doing your best. Frustration and anger may come at the same time. Do you have someone to sit in for you ? You definately need a break. So sorry you are going through this.
