Logotherapy and a bedridden old person.

My mother recently [18-Sep-2020] died at 88 and she was on bed for 5 years. Towards the end everyone was literally praying that she should die. Why: There was no purpose being served in keeping her alive. She was in pain and everyone was tired of caring for her.

I read "Man's search for Meaning" as early as in 2002 and I'm a very strong believer in the basic philosophy of the unconditional meaning of life: Life has meaning under ALL situations, repeat ALL situations; that life's meaning is absolutely unconditional and life has a meaning till the very last breath; the meaning is there not only in achieving but also in suffering bravely; that we can achieve meaning in three ways: through achieving, through experiencing and through loving.

I was watching video https://www.youtube.com/watch?v=jTxOiq3V7Bw&t=2401s of Kuber Ross in which I watched that some people in this situation actually think of committing suicide. I was thinking what I would do in a similar situation.

Recently I also read: "Death of Ivan Illiach", "The Last Lecture" and "Tuesday with Morrie". I still could not get answer to the question.

How can a bed ridden person, in the situation in which my mother was, can find meaning in life?
