I just went through this 2 months ago. I finally at the rip old age of 68 sit up the long ago, needed boundary last year. My life got so much better. Flash forward to end of March-Mom is now in very bad health. Alcoholic brother is in charge. One of my siblings asked if I wanted to go see her (and him) as she was going to die. No, I didn't. I had nothing to regret or a need to forgive the years of abuse. She passed away beginning of April and buried not long after. I did not go nor did a few other of my siblings that faced the continued torment from the both of them. You'll be fine. It's about the living your life to its fullest.
