As a caregiver for over 40 years for my brain injured daughter I have had to find a way to not be so stress. I have three areas I make sure I address properly every day...eat right, get enough sleep, and do some form of exercise even if it was 10 minutes a day. I also take time away from my daughter and let others care for her. If I don't take care of myself and get a break regularly, I am not going to be an effective caregiver. Stress is involved in care, not question, but we have control over managing that stress. Talk to your husband and alternate care while the other gets a break, reach out to neighbors who can sit with your loved one for an hour or two, others have used people in their church. Or hire a in home care agency so you can both get a break. Remember you are doing the best you can and that is what matters. Take care of each other to take care of your loved one.
