How does DBT help

I have BPD and PTSD. In my experience of trying three different DBT groups, two of them online were ran almost like a cult. The group mediators would corner us and make examples of us. The skills blatantly exacerbate any symptoms of PTSD (how are skills to cope with trauma inflicted on us a “myths”? What hope is there for us with BPD if the very therapy that is supposed to help only hurts? It’s like healing a blind person by telling them not to be blind in the first place. How is a person with BPD supposed to take pressured criticism from group leaders in front of others? Is this supposed to work??

I have BPD and PTSD as well. I didn't find my DBT group helpful, but the skills are(I had a therapist that basically printed out the workbook and gave it to me one handout a week). It wasn't at all "your coping skills are myths," but finding ways to manage impulses and destructive behaviors (like learning to recognize when vulnerabilities are higher than normal and I'm prone to doing things like drinking, disordered eating, and self harming so I can take steps to try and avoid those harmful coping skills/reactions and replace them with better ones).

Yeah, the group I was in sucked. It was like 50 minutes of going over the "homework" which was really more a couple members talking about their sister's sewing shyt or something stupid and 10 minutes of discombobulated lesson that wasn't even out of the actual DBT book.

Truly, the homeworks are never deep, it's always like about an argument with a coworker or something. I am getting worried about SH consequences I'm beginning to feel. It's so hard to stop. I don't even know what "splitting is". If DBT is supposed to be helpful for people with BPD then why do they not even acknowledge these things as pathological brain illness disorders and more of a "you're misbehaving", it's your behavior...I mean what symptoms did Marsha Linehan even exhibit that remotely resemble BPD? She had a narcissistic power play by housing poor people in her house. Read up on her. I swear she does more harm than good. If you think DBT isn't for you, if you're struggling in group, then get out as soon as you can. Trust me. They will make you feel worse about yourself when you actually have so much to offer and a Real Illness and not just misbehavior due to coping myths. Linehan should crawl in a hole.
