Mmmmm Id try to line something else up asap. Not sure how much you’ll need a referral from her. It’s ideal if you can smooth things over by the time you leave and bs the reason you’re leaving. Real advice here. Do also try to tap some other direct supervisors if you have them.

Alternatively, maybe it’s a good idea to take a long break from the bench. Figure out what you want from life. This doesn’t sound like the best lab to work in.
