Kill a relative or two as a final favour. Check if the wife still wants to live, check if I can be bothered to carry on. If so I’d either head into the mountains or down to the coast (get a boat) and try and get away from population centres for a year.

Edit: Sorry, just seen “selfhosted”. I’ve got about a terabyte of stuff on sd cards - super packable. Those, a handset, a wind-up radio and solar phone charger.
