I'd say that depends. If I've retained all the knowledge from my past life, then I'd say a restart. I can't say for sure whether things would turn out better or worse, but I am morbidly curious. At the very least, I'd be able to call CPS on my father and get him arrested. In this timeline, he's basically gotten away with every horrible thing he's done.
If I don't remember anything, well... I'd probably just choose to stop existing. I can't really see myself doing much better than this without any supernatural foresight.
