Oh I'm sorry it's delayed for you

It's really a widely used modality, imo...whether the actual "empty chair" is used or not... and yes, it can be quite emotionally draining and upsetting. Sometimes, if you really allow yourself to get into the scenario, you'll find yourself saying things that you haven't dared voice and probably haven't thought in a long time... but it's good once it's out, and can be very freeing.

I wish you well with this canders, I'm sure that your low self esteem has to be coming from what you think (or they portrayed to you) they think/thought of you.
