Welcome Pickles: I'm so sorry about what you are going through with your mom. Sounds like you became an adult at a very early age. That's a lot of step fathers and moving around. Has your mom ever been treated for BPD or some other mental illness?
So what brought me here today? The wheels fell off again. The emails she has sent me over the last week are ugly and mean. She says I am the worst daughter and clearly not a Christian because I am treating her awfully and like she is a burden. She said she will have to try again later in life to have a relationship with the grandkids because I am blocking her every attempt. (These are not true) She also said that I clearly have anger towards her and frustration that I am not moving past. (This is probably true)
SETTING BOUNDARIES can help you. Boundaries are for your benefit and are up to you to enforce. Your mom won't like them, but if you are consistent, you should gain some benefit.
When she sends nasty emails (voicemails, texts), you might want to block her for a period of time. Some people like to have some comments ready in advance for phone conversations when they enforce a boundary to terminate a conversation. They may say something like, "I need for us to have a mutually respectful conversation. I hear that it isn't possible right now, so I have to let you go. We can talk at a later time"
FOG - DEALING WITH FEAR, OBLIGATION AND GUILT is helpful to read about.
I would love to know how you move past the anger and frustration just knowing they are going to do it again?
Have any of you just decided that it is enough and you want to get off this ride with your Mom?
Many people struggle with the fear of the next episode of emotional upheaval. Some people even say they think they would feel better the behaviior was consistently bad, as the anxiety of not knowing what will happen seems to give them more anxiety.
Some people go no contact (NC) or limited contact (LC) and others go back and forth between both. It's up to you to decide what is best for you and your family.
The information below can get you started with some basic tools.
VALIDATION (or minimally not being invalidating), can be a productive tool to use. It doesn't mean that you agree with your mom's position, just that you acknowledge her feelings.
The two lessons below can be helpful for you to avoid arguments and drama. At the end of the article on the Karpman Drama Triangle, there is information about healthy communication triangles.
