6 months seems not long to me... But I can totally relate to this what you wrote... Once my T said, that he thinks that for next few weeks I should still come to therapy (I almost freaked out - only few weeks?!),but then another time he said something like, yeah probably after some months we'll solve this issue, so once I asked him about it and he said that he doesn't know, it might be few months or many years but it will be when we both feel that it's okay first to reduce the meetings' frequency and then to stop but it won't be like a strong deadline that we know the date and that will be the absolute end... Maybe you could ask your T, how he sees the ending process? Would you be able to come back if you feel so even after the official end?
