Stress and Anxiety are a Delusion?

I've been off my anxiety meds a few days. I've noticed that my leveled out stress and anxiety haven't changed, since being off.

Either that means the meds helped alot. Or it was all a delusion, and the meds helped in the form of a placebo effect.

If my whole thing with intense stress and anxiety has merely been a delusion. Then it must of been a layer of my psychosis created to bury my emotions and myself in it. As well as silencing my interpretation of other's emotions. That is a disturbing thought. But not outside the realm of possibility, with how I mentally function.

I continue to learn more as the days go on. Just how deeply interwoven, and complex, my psychological tramas and issues are.
