Yeah I realised this was very much how I got into a state of burnout in the first place - and I was staying in a role through guilt, not enjoyment.

I guess from your comments and my situation it should mean not returning to the role.

It's very rare that "going back" ever turns out well or as people hope (there are a few exceptions).

Keep in mind that you left for a reason...and the only thing you can really change is you...have you changed so much that you are missing it? That you can't move on without it?

My advice, as long as you have other reasonable options, take one of those paths instead...
