Welcome to the forum, Pnutt and Venkata. We ask that new members start a new topic to introduce themselves and their situations, rather than replying to someone else's post. This is to prevent you from "falling through the cracks" and not being noticed.
Venkata, I am so sorry about your mom's death from liver disease. It must have been very rough on everyone.
Pnutt, you do need some help or you are going to burn out fast. If your brother cannot be there, perhaps he could provide for someone to come in a couple of times a week to help out. Also, if your mom has less than 6 mos. to live, you should speak to her doctor about calling in Hospice. They will send nurses, even on a 24/7 basis near the end. Meanwhile, I suggest you read our educational threads, especially the one entitled Comments on Death and Dying.
You will get a lot of support here, so feel free to vent whenever you need to.
Hugs to you both,
Connie
