Asking the question, "is it time to...?" IMO, means you are close to reaching a decision, and now you need a plan to act. Over the past 40 years, I have placed my Mother, Father, Mother in Law, Sister, and lastly my husband into assisted living or care of some type. Each situation was very different and never simple. Everyday, ask yourself, what percent of your day is caregiver versus caring for yourself? At some point, is it unsafe for you and your family member to continuing being a primary caregiver? When you place a family member in care, it is not the end of a relationship, it is a new type of relationship. Quality of life for the caregiver directly effects how well you are caring for your family member. Others may say cruel or hurtful things to you, but trust your judgment and live your life to the best of your ability. I don't mean to be blythe by this comment, truly, I know the heart pain that comes with these decisions. As one of my favorite authors, Scott Peck, begins a great book, "life is difficult". It is your life to choose how to live it.
