Help, been at it 7 years suddendly became 11 years!

Mom passed away, and after 11 years of caregiving my work is done. It got really bad for her the last few months, but I NEVER gave up and, thank God, I never fell apart too badly. I suffer from arthritis now, I also weigh too much. My house is upside down. My siblings never helped out either. Mom even begged one of them who lives down the road to please come see her and spend time with her, but he would rather go to a ball game. And now she is gone and he can never get those years back where she was alive and he ignored her. Also, two of the siblings have died. They never saw her or called or sent flowers. My dear hubby will tell me they did not obey the 5th commandment! True indeed! I spoke to one sibling Christmas day and I said Mom is getting worse, he said he would fly out in a week or two and, five months later, he finally made it but it was now to visit her in a mortuary as I made arrangements for her burial. It was so hard all of those years, some of you may remember me. I have not been on this site in 3 years...wow! I guess I have been busy. Mom was 24/7 care, dementia, hallucinations and much, much more the last 4 months. For those of you still caring for a parent or spouse, God Bless you. You are all Angels and have all earned your wings. I'm here now if I can offer any advice? I don't know? I now have to re-learn being a wife and a mother to my own. Take care everyone.
