((((Griffe))))
you have never bogged us down with anything...this is a support site and we're all here to support each other...and you do your fare share of supporting too...so please NEVER feel like you are bogging us down...true friends take the ups and the downs, the good and the bad.
to answer you're question...i've never been to a support group specifically for ptsd...i've been to mental health support groups where it's like a social club. we all got together to play pool, cards, talk and we all learned as we went along about each others problems so we could support each other.
and as for this "friend"...can you change your phone number so he can't abuse you like that? just a suggestion, sorry if it's a silly one.
and please...DO keep posting, we like helping and supporting you as much as when we like it when you help and support us.
also please remember....TRUE friendship is a two-way street.
