Hi simon33
Welcome to bpdfamily Your mother's behavior sounds quite draining and difficult to handle. You say you moved home to help your parents after your mom got home from rehabilitation. The way your mother is behaving now, is this something she also did before you moved back? How was your relationship with your mom when you still lived in another state?
Your mother has been to a therapist, do you know if she perhaps has been diagnosed with any mental, emotional and/or behavioral disorders?
The situation you're in is quite difficult and sounds like it might require you to set and enforce some boundaries with your mother. Perhaps you will benefit from reading some of the material we have on here about boundaries:
Boundaries and ValuesExamples of boundariesI also recommend you take a look at an article we have here about fear, obligation and guilt (FOG). You mention your mother being very controlling. Do you feel like she uses fear, obligation and/or guilt to control you. Here's an excerpt from the article:
... .fear, obligation or guilt ("FOG" are the transactional dynamics at play between the controller and the person being controlled. Understanding these dynamics are useful to anyone trying to extricate themselves from the controlling behavior by another person and deal with their own compulsions to do things that are uncomfortable, undesirable, burdensome, or self-sacrificing for others.
