I ran out of characters in the OP, but one thing I'd add is that you may not be able to apply all three rules on day 1. If someone is severely depressed, it will be difficult to do #3 and be randomly active. It can take months or more of just focusing on #1 and #2, removing psychological obstacles, self-hate, etc. until they even begin to have the energy to do #3. And you probably have to start #3 with simple stuff like diet that doesn't take much effort to be experimental with. Don't force anything, just work it up slowly, gradually, at whatever pace they're capable of. And stop, rest, and recuperate when needed.
