I don't think it was a bad idea to send him another email. I do that sometimes with people I know who are not very good at keeping up correspondence and it lets them know that I care. I also don't think it was a bad thing to let him know how your diagnoses effect you. You may have gotten a little aggressive in the end there tho with the religious comment… but I don't know him, so I really don't know.

I hope that he is understanding and you do hear back from him soon
