I think your T is ill too , and should not be practising. I do understand this as I'm having a problem with my best friend of 25 years. I think there's something wrong with her but it's affecting me adversely ( she's turning into my Mother ). And it's hard to pull away - my T says I'm not an abandoner even though I've been repeatedly abandoned myself. We do play out the same thing , trying to fix and wishing this person would be normal so they can be what we need. I do hope you will see your tutor or another T so they can help you with this. It's an awful feeling.
