Stimulants help me ignore the pain and fatigue from my lupus. Now I happen to have ADD as well, but I know people with very treatment resistant depression that were helped by stimulants. Also the strategies I learned for AS/ADD I taught to some NTs with other types of issues with success, because a lot can be applied to a wide range of issues. Sometimes "just" depression makes it hard to start things and organize and all that, and then an ADD strategy can help.
