I related to everything you felt many decades ago, and I moved out. I've been independent and healing ever since. Was it tough? Yes. I even spent many times homeless. I know that's not the ideal, but homelessness was way better than the trauma triggers and painful feelings I got being around dysfunctional family. My mom wasn't abusive, but she was neglectful. She and I are close in words and in caring for one another, but we're not close in terms of bonding or feeling this emotional connection. I feel more emotional connection with my therapist and with my friends than I do family. But I've been physically and sexually hurt by men in my family and otherwise, so that's a layer that you might not experience.

I can definitely understand childhood emotional neglect issues though.

My friends who felt stuck in their relationships with their toxic family members, or even felt stuck with being parentified to one or more family members (a parent, a sibling, or both), said that they found healing and freedom the moment they chose to leave. That decision took some of my friends a long time, due to the guilt they felt. Some took years, whereas others took just months. You'll know when the time is right.

You do want to avoid being homeless though, and you do want a plan. Since you're in physically or sexually endangered, or being reminded of physical or sexual abuse, you might be able to set up a transition plan before you move out. You can plan to move out, and you can prepare your family in subtle or direct ways for your moving out - that is, if it is safe to do so. If your telling them that you're moving out will cause all sorts of arguments and rejections, especially cultural rejections, then perhaps you can wait to tell them you are moving out until the last few days that you are there, so that they don't just throw you out on the street or something.

Every situation like this is different, but almost all people who have moved out felt better. They still struggled, but they felt better.
