Well... the Skeezyks is no kind of expert with regard to this sort of thing. But, yes, it sounds to me as though you've been struggling with the same sorts of thoughts & auditory hallucinations for quite a while now. I guess I'm sort-of surprised that the doctors you have mentioned this to weren't concerned. But, then, as I think back over my own experiences in the mental health system where I live... I guess I'm really not all that surprised after all.
The good news here, it seems to me, is that you seem to have perspective with regard to what you're experiencing. If you were having these experiences & were convinced they were real... that, I think, would be a more serious situation yet. Under any circumstances, I think if it were me, I'd want to keep mentioning the experiences you're having to whatever mental health professionals you're seeing at present. Just my personal opinion... for what it's worth.
