I should have added of course, all depends on how strong that transference is. Not everyone experiences the same amount of transference obviously, and some persons have less issues with it (as they may have less attachment and related anxiety problems in general). In such a case scenario I can see how (if you're lucky enough to have found a T who can work with this well, and they seem to be very rare) you could 'work through it'. But if you experience it as torture, as the OP says she does, and as I have experienced it multiple times in my life too: run.

You are very likely just triggering episodes of feeling unworthy of your self, of love, insecurities and do I know with this relationship, and I don't believe at all that staying in this connection is going to improve that - on the contrary: as you will very likely face continuous feelings of rejection, isolation etcetera, within this connection.
