I felt that way too. I didn't talk to my mom for a year because I couldn't take the way she was and what she did to everyone, holding on to a grude that just fueled the fire. She died recently. I wish I could have made amends but its too late. Just remember...anyday could be the last and would you be ok if you had to leave things the way they are?
Love your mother for one day she will not be around, Learn to forgive no matter how hard.
