Asking for different perspectives about this statement?

BACKGROUND: So, I want to take a step back from my family because I’ve realized I’m holding on because I want their empathy about things they’ve done to me, but in therapy the other day, I expressed to my therapist that it would “never come because they don’t have the empathy to process the issue.” Soooo, the next step is to just move on with my life.

THE ISSUE: For some reason, my sister and mom told me that if I leave and don’t respond, then they’ll assume I’m “dead or trafficked.”

What do I do with this statement? It seems no contact will result in the family assuming I’m dead… Low contact would also make them think I’m being trafficked because how dare I not ask for help or react…

Is it time to just worry about me and stop stressing on them? I just want to leave, but they’re being very dramatic and not understanding how that statement hurts/makes me feel like they only assume the worse if I go too far from them… This is manipulation, right???
