Transference is reality. The feelings are real and so important to heed and address. They just may be disproportionate in terms of what evokes them, a combination of feelings based on current events and old ones. Transference is not the type of thing that just disappears overnight or after one good session... it's a pattern of relating, it's deep-seated. Transference typically takes some significant effort and ongoing discussion to resolve.

I actually think that acne analogy is pretty fitting... transference is like adolescence, lol, and there will be flare ups and clearer periods, but it won't really resolve until you hit emotional adulthood and finish processing everything in your past that still needs attention.
