Janet, I didn't want to give too much advice so soon after your upset with your Mom, but V is giving you some good advice here. Your mom will not be around that much longer, and if at all possible, you need to take the high road on this one.
My own mother passed away in 2000 and I was her only child, so we went through a lot together, good and bad. Life is not easy. If it were, we would not have a need for God in our lives.
You may wish to read and meditate on 1 Corinthians 13, especially verse 7.

Even though your mom is not showing love as you would like, you can.
Love and hugs to you!!
