Delusions about faking symptoms?

Hello all,

First of all, I'm currently in the process of getting a diagnosis (psychiatrist suspects schizophrenia). I had a 5 months long psychotic break earlier this year, now I am better but still have symptoms.

However I have this thing that I believe that I'm somehow faking my symptoms. For instance, one morning I heard voices and saw shadow people, but then I was "normal" by the afternoon. And then I would tell myself that I didn't actually experience anything in the morning and I'm just faking it (like I have imposter syndrome or something). This also makes talking to the psychiatrist difficult, because I often convince myself that I'd be lying to him if I told him the things. Anyone else experienced this before? How do you cope with it?

Sorry this post is a bit random, but this is pretty distressing for me haha
