You can keep turning this around in your head over and over and over again Lori but all it will do it feed the anxiety. It won't put you in the place where you will find solutions. My suggestion would be cognitive behavioral therapy focused on learning to recognize and change thought patterns. There are also a wide variety of non-sedating anxiety medications. I would also suggest finding a support group for caregivers. Your Area Agency on Aging may have some suggestions how you could tap into those resources. You deserve to feel better and be living a happier life than you are right now and I hope you will allow yourself to take steps to feel better.
