I think it's a tricky one... I think I'd be more likely to open with the fact I hear voices because it's my major symptom & it is something tangible. That's then likely to lead them to the question of what is wrong with you at which point you can give the dx you have. That seems like a fairly natural way to cover things.

I would certainly try to avoid speaking too much about delusions and/or paranoia because that is likely to weird a person out or even scare them if they are not very well clued up about psychosis. It's not something that is easy to relate to & probably the aspect which most would consider most "crazy".

That's not to say you can't talk about that but I would leave that up to them to bring up at first. If they know & are comfortable with your dx then it is perhaps something you could bring up later.

I would also try to keep it quite succinct at first, it's a lot to take in just at face value. You don't want to overwhelm them by going into detail about what it entails for you until they are comfortable with it, which won't be when first bringing it up.

I certainly know my friend at first found it quite hard to stomach when I told him I had schizophrenia (which was the thinking at the moment in time) ... he did ask about what symptoms I had but I kept it quite to the point. He didn't have very much to say as I think it was a big shock to him as it would be to most people. However after a few days he was quite keen on asking about & discussing the illness.

All in all, just play it by ear but I wouldn't reveal too much when first bringing it up. Just stick to the highlights.
