I'm with pbutton on this.. I struggled for ages, but eventually I too felt as if I just had to 'give in' to it. Like pbutton I didn't go as overboard and crazy as I thought I might (one extra session, couple of phonecalls, a number of emails.) I still don't actually contact her a whole lot, well.. maybe - about 3 emails a week?

But therapy has been quite intense lately, and this way, we've made a lot of progress. Up until I 'gave in', I was pretty much keeping T at arms length, not letting her in, not letting myself depend on or really trust her.. not that I realised that at the time, I just thought I was fighting what I saw as an unhealthy amount of attachment - and fighting being vulnerable, not putting myself in a position that may result in my being 'rejected' - but in doing so I don't think I was really connecting. I realise now that this is a pattern in my life, that I don't allow people to get close to me, and don't really emotionally invest in relationships with people.
Now I feel I
can reach out to my T - and I know it's okay, and the weeks are passing and I'm feeling more secure in knowing it's okay - I do feel less urgency to do so. I know she's there.
As difficult as it is, maybe this is something you need to talk to your T about?
