Senior Caregiver - Full-time / Part-time

I'm looking for companion care for my mother in her late 60s. Responsibilities include light meal preparation (lunch or snacks). Could possibly help with transportation to Dr. appointments or errands if needed. Would love for someone to come in a couple times a week just to sit and eat lunch with her and help her with light exercises/walking around. She is dealing with grief and depression from the loss of her husband and is not taking care of herself properly. Hoping to get her back on her feet and feeling like herself again.
