You can explain it either honestly with medical issue during an interview, phrase it as a sabbatical where you focused on something else or yourself for a year

You can explain it either honestly with medical issue during an interview, phrase it as a sabbatical where you focused on something else or yourself for a year to figure out what you wanted, and did projects on the side instead of working. Or a "fun" way is to claim you worked for any government agency who would never verify or deny that you ever worked for them. :P
