Some members of my family were absolutely horrible in their treatment of me when I had a mental health issue. I feel, in my case, it was these same people who treated me so badly that is what caused my emotional illness in the first place. It is understandable they would further mistreat me, rather than giving me love and support.
Throughout this whole ordeal, which lasted decades for me, I kept saying it is not all me, it is mostly them. After learning about narcissism, I now have understanding that my thinking was right.
For mental health issues that involve relational issues with others, it is important to look at the behavior of all those involved.
Hugs to you, Jesyka
