Sailaway,
I'm sorry you are not feeling safe. It is so upsetting to feel that way!
I think you are probably right where you should be. I think it is inevitable that bringing things 'up front' brings a lot of uncomfortable feelings with it, including and maybe especially about feeling safe.
Good for you for asking if you were safe! That is a good way to care for yourself and it is always good to express how you are feeling.
About thinking of quitting. That too, along with wondering if you are safe, is a way of wanting to not have to think about these things and is a way of saying just how much it hurts to remember and think or talk about them. When you think of quitting, think of it as another symptom and tell yourself that thinking of quitting is all the more reason to stay in there.
Hang on! Things will get better. You are going the right direction!
