Friend For Sister In Long Beach

My sister is in an assisted living location and can only go on outings with family, friend or caregiver. She is wonderful but has been through a lot. She suffers from mental health and her mood changes sometimes. She really thrives when she is able to do her favorite things like getting coffee, barns and nobel for a book, hike, beach or get vegan food which is her favorite. I am looking for someone who has lots of experience with mental health of another person and who really has worked as a caretaker. Not just anyone because she needs someone strong who can handle outings if she is not well, etc. Please let me know if you have experience. This can be a good opportunity for someone to do something fun too with her. Must have a safe and new car. Thank you.
