hi erin-
i empathise and have similar feelings of foreboding. i also feel oppression, even though i can't put my finger on what i feel oppressed by. it's just a vague feeling that's always there, even though i am in a safe place now, away from the alcoholic madness.
i'm no expert on this, but i think, for myself, that i feel that this is the fallout from living in a pressure zone with my alcoholic. so many times, he crossed the line of what i thought he would do. when i thought it couldn't get any worse, it did. when i thought, surely he's not capable of that, he was.
after years of not being exactly sure what i would come home to, or wake up to, i think that the feeling of oppression/foreboding is residual from this trauma.
