Hi Living In Chaos, not sure about the mandated reporter bit in your country sorry, but the fact remains that if you aren't ready to/don't want to tell him about what happened you don't have to. I hope you'll be able to tell someone IRL when you can/when you're ready, but you don't have to tell him.
And there will be G.P's who recognize that anything attached to your diagnoses can be between you and your psychiatrist (afterall anything health wise/need to know in any treatment should be passed on to them anyway).
Now I'm not up on your health services sorry, but is there another G.P. at the practice who you could book any further appointments with?? If so.............easy to come up with some "trivial" excuse as to why you want to try someone else, he is new anyway so shouldn't lead to suspicion??
Otherwise, I'm wondering if maybe your psychiatrist would be able to forward a letter to your G.P. saying that the details behind your diagnosis haven't been seen as "medically relevant" (in a polite way, of course!!!).
Otherwise if we're talking usually irregular physicals with him???? Do you think it could make a difference if you were just more assertive with him next time and told him that it was "private information" you weren't prepared to disclose, maybe your psychiatrist could advise you on what to say?? I know it must have been so hard for you this time and I'm really sorry about that but just an idea..............
