Resentment toward past wrong and injustices will make your present caregiving role very difficult. Let go of what was and concentrate on making what is healthy and productive. Develop a habit of enjoying shared activities. Releasing the roles of caregiver and care recipient allows you to enjoy each other. Begin to think about your future.
All situations vary.
I encourage you to always consult your health care professionals to discuss your individual situation and the best course of action for you and your care recipient. I may help a relative soon. I am beginning to help. I am helping. My role is changing.
