I absolutely think so with ex-longterm-t. I'd been researching names my pdoc had given me, when I stumbled on L's psychology today profile (she was not on his list). We just clicked from the first phone call, it seemed something like fate, especially since I saw her for over 10 years.
The first 2 t's I'd tried long before finding her, not so much, except for, they definitely taught me what I wasn't looking for in a t and that was important too.
