Did you know that emotional dysregulation could have a physiological basis, and therefore, managed with Functional medicine ?
Also, I thought your explanation was very coherent and clear. Maybe if you share it with your Mom, she would appreciate the level of pain you experience. This is like PTSD, and there are therapies that help with this. I like EFT, but there are many other modalities. Just know that you are not alone in this, and that there are no persons who are completely immune to dysregulation. We all have different genetic and environmental, stress and lifestyle triggers at different times in our lives. If we can tap into the timeline sequence of these triggering or mediating effects, we can fix the underlying problems.
I hope this is encouraging, and I applaud your courage to seek help !
