Hi nomore12345 and welcome to bpdfamily
Being raised by a BPD parent is often very difficult for a child. Has your mother been officially diagnosed with BPD and/or ever gotten any targeted treatment for her issues?
You mention also having struggled with BPD yourself but through hard (and painful) work been able to get your own problems under control. Were you officially diagnosed with BPD?
BPD is a difficult disorder but there are definitely people who through hard work and commitment have been able to better manage their difficult thoughts and emotions and I am glad you were able to do this too

You mention having cut off contact with your mother. When did you go no contact with her? Did something specific happen that led to this decision or was it more the accumulation of everything you've been through?
