Toxic People

I am unashamed to admit, I meet with a psychologist every other week.
Recently, she helped me put in perspective, Toxic People.
Every time I allow a toxic/hateful/negative/bitter... person into my life and whenever I visit someone I care about who is toxic..., I'm willingly downing a shot of poison.
That person knows it on some level and gets his/her strength and twisted pleasure from causing me pain.
We have the right to protect ourselves; so building new boundaries, distancing ourselves from the poisonous person.
It's so not an easy change to make. Three of the people who've plagued my life and well-being going back as far as being a new-born. They're family. Immediate family.
But. They take issue with me. Just that, THEY have issues; not me.
After addressing the main reasons they have for hurting me:
"Your scars make people uncomfortable. You should cover them up."
I was born, born into circumstances this person wanted (and deserved); so this person tortured, stalked and threatened my life, and continues to play on my emotions to see me unhappy.
The other person is a complex case, but the main issue is my openness. I care. I don't discriminate or put conditions on my feelings toward, treatment of and willingness to be open to others. This person is an extremist of sorts, who may be getting better, I hear.
So, even if a parent or sibling or close relative are the source, you have the right to separate yourself from them.
