Also living in Hamburg. Have you tried 116117.app to at least get a first appointment? I got lists and lists full of phone numbers, always got rejected or waitlisted, but found a therapist quite quickly near me using this first talk. Nobody told me about this, had to search a lot. I hope this helps.

Getting the first appointment was easy, it’s the follow up treatment that has the extremely long waiting list

Many will offer a first appointment for preliminary diagnosis and to check if they can help you, but then you are put onto the waiting list
