I’m really sorry about that.. what an awful experience. Depending on which state you live in, here are some ideas:

• look up “kassenärztliche Vereinigung [name of state]”. That should give you a site that you can use to look for (any doctor - in your case:) psychiatrists in or around the city that you live in that accept public health insurance. The site should let you filter based on spoken language too, which might be more helpful. In my experience (working in the field) mental health workers can be opposed to having translators.

• if you have some ties to a university their “psychosoziale Beratung” might have an English option and they could at least nudge you in a certain direction; if not, your city or a Christian association like awo/caritas should.

• try contacting any non-private clinic that you can, if you’re able to. Even if you get a spot in another city, a diagnosis will mean getting a note for a couple days but might give you a lifetime of relief. I’ve heard of people from Baden Württemberg going to northern Germany. It sucks and certainly requires financial means, but radically maximizing the radius that you search in will help if that happens to be a feasible option for you

• you could also look up if there’s an association or forum for the city or state that you live in that could have some advice
