Anxiety and fear are pretty much the same thing. I think you are wondering if its just from having an anxiety disorder or if you are getting delusions that are more psychosis based?

Its hard for of us to say as we are not in your shoes but I can relate to irrational fears. Not of objects but of terrible things happening to me that are not possible when I think more rationally.

So it could be that your severe anxiety just makes everything seem so frightening that now even harmless objects are scary or the frequent change of meds has effected it or there is some other mental health issue going on.

Speak to your pdoc and see what he/she has to say. I would say though that you seem to know' that your fear of the objects is irrational and I would have thought that if you were truly delusional you wouldn't necessarily know that? just my opinion.

Good luck and take care
