ADD and Disability?

My ADD spouse has been unemployed for over 15 years.  Now that he is "diagnosed" with ADD, he claims that he could never work at a real job because he can't deal with people with his ADD.  I have been the sole bread-winner all this time, which, ironically, he resents, as he says it gives me all the power, and apparently makes him feel like a big loser.  I have been at my job for over 20 years and am really tired of supporting him, I need a break myself!  He's been taking Strattera for over a year, and he thinks he sees a difference, but I honestly think he's worse, has many more "explosions" & over-reactions.  Whenever I've suggested that maybe he try to collect disability or social security, so that he's contributing something to the household, he blows up!  We had a huge fight recently where he announced he was going to leave me and collect alimony from me!  I'd really like to understand him, but it seems like he gets to "have his cake and eat it, too"...just wants me to leave him alone so he can continue to pretend to work: whenever I ask him to at least accomplish things around the house, he gets belligerent--as I'm typing this, he is on the computer, has been for most of the day.  He insisted that he get the iPhone so he could be more in touch, and now that he has it, I see that its just another extension of his computer, only now he's connected 24/7, I can see how important it makes him feel, maybe it will help. So--Is ADD considered a disability?
