"Attachment therapy" - any communities for people who've been through this?

Hello, first time poster here, please let me know if this isn't the appropriate place to look for resources or community.

Around 2002-3 I was subjected to "attachment therapy" treatment as a minor. To be clear, I am referring to the unscientific, now-discredited, dangerous form of therapy spawned in Evergreen Colorado that tragically lead to the loss of multiple lives, NOT attachment-based therapy.

I've dealt with the shame and trauma of this experience for a long time, and have always felt like no one could really understand what I went through. Having finally worked through this with my therapist, I've recently discovered "attachment therapy" was an international phenomena. There must be a community of survivors somewhere.

Does anyone know where I might find other people who've been through this, or know of an active community?

Thanks in advance for your help. Apologies if I'm not exactly posting in the spirit of this subreddit, just hoping there might be other people out there like me.
