I think the problem is that the relationship became something other than therapist and client. Not that I am saying that is always bad, BUT it is almost impossible to continue therapy when the relationship changes to something other.

By interning in T's office and "being her friend" the therapy relationship was broken....the boundaries are all messed up. It is almost impossible to go back to a traditional therapy relationship with boundaries, because you have broken the rules, per se.

Perhaps you can look for another T, but figure out a relationship with this T. For example, calling once a week or having lunch.
