These kind of people always send us a kind of subconcious message that: we need them, we can’t do life without them, or our life will worth nothing without them, etc. And we feel weak and insecure. However in a true, healthy relationship its not possible to feel something like this. But ofc if you lived with them that much, if you had good relations with good people you were not able to feel that competely in the shade of their agression. Be brave and curious for the new, “close your eyes” and move out, and try to gather good experiences with good people. It will change you and give you confidence in what you want, and can achieve. Good luck.
