With what we know of her mental state, "good enough" appears to be a pinnacle of what's possible...for the moment, at least.I personally think "happiness" is irrelevant, especially for someone with depression as severe as she's described. She's been functional, has the ability to experience joy at times, and is mostly not self sabotaging while continuing trying to grow her channel and herself.
And, again, incomplete information, but just judging by the streams, she appears to be in a "good enough" state most of the time.
