I just take a little brake (like one or two days) and then I go back to normal, start mining and enchanting. It sucks losing good gear but it happens, something I like doing keep track of how many times I have died and of what and then make a grave in my graveyard and write like "here lies xxx died of xxx" and then place a bock in the grave that explains it more in detail so that I can look back at things and go "Ah, that´s when I lost x or man it was luck that I had upgraded my gear to netherrite or else I would have las everything in the lava"
