DID I HEAR YOU RIGHT??? You wanted to go to a support group for PTSD and they nixed the idea saying you shouldn't nurture it? Obviously any support group they know of is just a bunch of whiners and not real therapy... I'm not a group person, and plus my injury issues aren't common themes for PTSD groups (so many are child abuse, or military combat) so a group wouldn't do me good but worse.
However, if you are in a similar group and the T does real group therapy, then maybe being triggered by another's story, and having the T work through it with the group as a whole (for I doubt you would be the only one triggered) that is hardly nurturing it.
Unless you've already had the discussion, I would ask exactly what their definition of nurture is, and what their fears are of you attending group.
It could very well be for your own good, as a T who does group might use a different method that your own T and confusion etc (or over work) could occur. But I'd still want to know exactly what they think. lol
I had taken a very, very long time (thank GOD for no limit insurance covered session) just for ME to be sure that the guy I was seeing who was an "expert" in pain and stress management. . . to be sure he really did (does) "get it". And yes, he does and once that was worked through, then I didn't have to continually feel like he really didn't understand all I go through etc. with the ptsd.
