ADHD and autism have positives. Somebody with either (or both) of those can, in the right environment, live a happy and fulfilling life.

Depression is, by definition, not living a happy and fulfilling life. That's why even though "No, your brain is different in the broken way" may feel wrong, it's not.

And to be clear, I have both autism and chronic depression. I would love to be cured of the latter, but the former is a core part of who I am.
