My heart goes out to you. Lost my mom three years ago. She was diagnosed with bladder cancer and we lost her six months later to a stroke. Glad you spent time with them now. My brother put off coming to visit them ( he lives an hour and a half away ) til mom had lapsed into a coma. I know he regrets it and staying away was a way he didn't have to face the fact mom was dieing. I really feel sorry for him. You did the right thing going and spending time with your folks now. And I know you will keep doing right by your mom too. Prayers for you and your family.
