Rag doll is a perfect description!!
This experience is a life changer, both physically and emotionally.
Re transportation to chemo: I think the American Cancer Society has volunteers who do this. I’m not sure if you call them directly or if the social worker at your cancer facility makes the connection for you. It might be worth asking about, even if it’s just to fill in for when a friend or relative is not available. Best wishes as you heal from surgery and begin the chemo. Sometimes I felt like I was living in an alternate universe.
