OH Sweetheart! Boy, do I understand what it's like to the the world's scapegoat. It sounds like you and I could have been twins....but I am older than you, and I have figured out a few tricks.
First develop boundaries. Honey, you have to be around safe people. Weed out the dysfunctional ones. Here are my iron clad boundaries....laws set in stone like commandments, that I follow. Maybe you can use some of these.
I will distance myself from
1. liars.
2. addicts (not just drugs)
3. People who have problems processing empathy (this is MOST important----if after you make an effort at "nonviolent communication" to express your view, and they still don't get you----LET THEM GO, major loose screw with processing empathy there, nothing to do with you)
4. People who are reckless and will not promote safety.
If you stick with these boundaries like glue, over 3-6 months, you will have much better relationships. I promise.
THEN, if you can calmly sit with yourself, you can process layer after layer of trauma, without having screwed up people mess up your self work. It is like a onion, just work with layer after layer. You cannot do this if the Epic Bags of Dicks (EBoD) folks are heaping on more adrenaline and trauma.
Godspeed, sweetheart, you have so much to offer. the world.
