How do I mentally prepare for a worst case scenario?

Worst case scenario is obviously some sort of hack/scam to lose everything.

I feel i’ve taken enough precautions to be ok but there’s always a possibility BTC never reaches a further price than it is already. I’m confident we will see new ATHs but I’d need to prepare to have nothing.

I feel i’ve taken every step of advice to keep everything secure, I could obviously go to the extreme of a security deposit box or something if I had true life changing money but unlikely it would get to that point. I’ve put in all the money I can afford to lose as well but I know losing it all would feel like a heartbreak.
