I am an only child of my last remaining parent. My mother is 94. I am 64 and just retired. I didn't think or expect to become a caregiver. It left me in a depression for which I am getting help. But everyday, when I go to visit my mother and do things for her, it hits me so hard that I will eventually be losing a parent and it's very sad to see her so old and getting age related problems, etc., I find myself worrying 24/7 and unable to enjoy myself and preoccupied with how to handle her issues and how to help her. Any advice will help. Thanks.
