I took tests for depression online. They were vague. Where can I get definite diagnosis?

No Self-Dx. Even if the tests on line were not vague, you still will need someone to help you explain the results. Number itself is meaningless, what's more important is the item analysis. Also, diagnosis is not given based on a single measure. There're several measures that assess whatever is needed for your diagnosis. Bottom line-- don't diagnose yourself, get a professional to do it.
