How does one get a healthcare appointment (psychiatrist) in the Netherlands?

It’s been a very frustrating experience trying to get to a psychiatrist lately. I completely resent huisarts as professionals. They just can’t make anything work. Then the waiting queue to real specialists is ridiculous (many months). How does one even get to get help here??

Upd: I have a diagnosis that my huisarts / GP is well aware of, and still no luck.
