Most simply put.... START OVER. I don't believe I would give up. Bitcoin is bigger than just one person having a bad experience and giving up. Plus, whatever mistake I would have made, I surely would not be dumb enough to make it again. Hopefully
Maybe you could say that because you haven't made a lot of money yet compared to others who invested a lot already.
I don't think I could start over again after losing all what I spent my time on. It will not be worth it.
