I had DBT as an inpatient which was really helpful. OT also very helpful.
What has not been helpful is short IAPT style therapy which always brings everything up then leaves me to deal with it once therapy has finished.
I was also referred to a DBT skills group in the community which was awful. The people running it knew little about the DBT skills, they allowed the group to be derailed by people talking about their issues and then let a man join who would talk about all the aggressive things he'd been doing. I left at that point. Baring in mind most with EUPD have suffered trauma it was awful they allowed it.
I could do with OT input now but it seems to have all stopped in COVID and never started again.
