There are some states that allow a person to decide to do that. The case I saw in the paper was a young lady diagnosed with incurable brain cancer and the pain and seizures would continue to get worse. She made a bucket list...checked it off...had a big good bye celebration and then moved to a state which
assisted her. She passed with her pets, family and friends surrounding her.
I don't know how that whole process works. I'm glad you posted today. I sent a pm to you because I was concerned about your well being based on the things you said the night before. Hang on and keep fighting. You're not alone.
