Hmmmmm. Hugs go out to you as I know (as many of us do) what you're going through. Does he read much? Because maybe you could pick up some books on the illness and some one people coping with loved ones with the illness. Then he can pick it up whenever he gets the time, and have it close at hand for quick reference (when the frustration begins and we all need some grounding).
I find journaling extremely useful as well. I'm not familiar with your coping techniques, but that's a big one of mine. Journaling allows me to vent, write about how the situation impacted me, feel sorry for myself in secret if I feel like it, and reassess all the details when I'm clear headed and done getting it out. That way you can talk about it later (instead of when mad) and empathize with what he goes through when you have an episode (that's what I call them:) ).
I'm certainly not a doctor, but hopefully some of these things will help you like they helped me. Just spend daily leisure time surfing around the site, I'm new too, but we can be new together.
