I am in my early 30s and am about the become the primary caregiver for my 85-year-old grandmother. She has congestive heart failure and diabetes, but is still of relatively sound mind. She is able to remain in her home for the time being. I've just moved back to my hometown and will be taking care of her (medical appointments, transportation) while working part-time. I'm wondering if anyone has any advice about particularly challenging caregiving activities. What tasks were the most difficult/time-consuming to coordinate? Was there anything that surprised you or you wish you had known looking back? Any help and advice is very, very appreciated. Thanks so much!
