Mothers day is fast approaching

Mother's day is fast appoarching this week we begin making our plans, it's another holiday in our family and in a sense for me it's a dreaded holiday all holidays are like this for me because of my mother I know that sounds harsh but let me explain she never really has been the mother that she should have been to me, My grandparetns took care of me and then I took care of myself when I got older. She always ruins the holdiays with her little fits that she throws and her smart elleck comments that she makes about everyone in the family. I dont know why my family keeps including her and allowing her to behave this way Im not going to say anything because it's not my decision to make because it's my uncle's house that we always go to and Im not going to stay away and miss seeing the rest of my family especially my grandma I just bit my tongue and move on but I dread it everytime it seems like the holdiays can't be enjoyable. Do you have family members that are like this?
