To try to pray when one is ill, when one is troubled with illness, and pain and solitude and loneliness... this is not what your heavenly father wants.
For persons sick and completely pre-occupied with their illness, in spirit, let such a person rest comfortably in his/her Father's arms, in his/her Savior's arms/ or in the arms of the Holy Spirit.
Rest there like a babe in his/her mother's arms. Rejoice in being with your God , He who created you. May such consoling confidence bring you to a profound rest.
This is not a time for struggling with words, or texts etc., be at peace and in rest with your God.
When you awake, rested and consoled, in spirit either by "looking" at your God, smile at Him and may the joy in your heart express your love for Him more than any words possibly could.
Do not be anxious, do not be afraid, no distractions... in spirit rejoice in being together, see His pure Love and care for you. Rejoice in your togetherness with Him.
