it's hard...i know, i wish i could just tell ppl that "hey i have a MI that's why...i was a lunatic last fall!" but they won't get it. hardly anyone will. people aren't as compassionate as you think...in my opinion...esp about MI. you just have to be vague when it comes to talking about your past and if you really know them, and know that they are true to you, then tell them slowly and gently, explain it to them, give em' some psychoeducation.
