There are many many other classes of medications for depression. SNRIs, tricyclics, mood stabilizers, bupropion is a completely different mechanism of action, even drugs that were originally developed to be antipsychotics are used off label.

I agree with others who have suggested that you should see an actual psychiatrist. Other prescribers just don’t have the same training and experience as a psychiatrist with a medical doctor license. There are lots of medications available.
