How do I get them to listen to me in regards to my diagnosis and to accept my marriage?

My parents hate my husband. They only tolerate him because I'll refuse to come to gatherings without him. They say he's lazy, only with me because I get SSI, and treats our son bad. They feel HE caused my son's MH issues. I respect them and love them but I refuse to have my son around people that bad mouth someone he loves and is part of him. No one would put up with my craziness if the didn't care, he's an awesome dad but usually is testy around them because no matter what he's in the wrong. He doesn't dislike my parents but my parents motives for things are very hard to understand.

Forget them understanding and accepting your DX. They won't get it. No one wants to hear there child is dealing with a chronic illness that may or may not kill them. I've become very honest with my mother because I had to ask her a question that she found out I was on seroquel. My father and I (I'm a daddy's girl) have got into full on arguments as he doesn't believe in maintenance medication. It was ended when I said "Well meds keep your daughter and grandson alive." I wish I could take that back as soon as it came out of my mouth.

You have to do what works for you for me it's always been insisting that they have no choice but to put up with my crap. They are also the last to know if my husband and I are having issues.
