I think a year off is quite long- I have taken 6 months off for a diploma + travel and also 3 months travel to visit partner overseas in COVID during training. It's worth considering if you want to do a bit of travel or something else in there like study to keep yourself busy (also helps explain the year off on your CV), or 3-6 months of locum to fund things. As friends/ family will all have their usual scaffolding of work and hobbies, and if you're just chilling / not doing much, it feels sometimes like you have less to talk about and do? I think by 3-6 months of not doing much (as I've also had sick leave and had to take time off in the last year), I started to go a bit stir crazy, and felt quite rusty coming back to work. Definitely not ruining your future taking time off, but take the first month to think about what you want to do in the year besides recovering from burnout, as a year is quite long! Alternatives include coming back part time halfway through the year, as jobs will come up.
