Definitely done that before... yeah, walking in to see t again the next time was awkward, but it was ok in the end. T didn't push the stuff I didn't want to really talk about.
Would you be open to trying to talk about any of it with t, even if it's a struggle? Those have generally been better session for me. Sometimes it's good to let the walls down a bit...
fwiw, t didn't think differently of me for letting go at those times.
