I've ahd auditory hallucinations and delusions. and suffer from MDD (major depressive disorder). Good self talk can help, medication can help, therapy can help, talking to anyone can help. It all depends on what works for you.

It may seem like you are getting worse, but thinking that you are getting worse can cause the symptoms to get worse... so be careful. (from experience) The mind is a powerful organ, and can be fooled into thinking of things getting worse..

again this is from my experiences, and it's been hard to live with "the voices" But it's doable, hard but still you can live with them.

And by good self talk, I mean thinks like defeating the thoughts, proofing that the thoughts aren't true, denying that they exsist. That sort of thing. I find that relaxation can help when when they voices return.

Good luck.
