Will anyone solve my partner's depression before 2027? [M$1,000,000 bounty]

Prediction market on manifold. My partner has frequent bouts of depression where she just feels ambiently sad for no particular reason, often to the point of crying. These bouts can last anywhere from a few hours to a few days. In total I'd estimate that she spends about 1/6 of her waking time depressed, though I haven't been keeping careful track. This has been happening for many years. She's currently 35, exercises for about an hour most mornings, mostly healthy though with a few dietary issues. She's talked to a doctor and has been taking fluoxetine, but it hasn't seemed to help. She's open to experimentation but will have trouble sticking to anything super consistent. If anyone suggests something specific that seems to have permanently solved the problem and that wasn't going to happen without your aid, I'll pay you M$1,000,000 or $1000 USD, your choice. (If someone not on Manifold solves it, market still resolves YES, but there's no bounty.) There will be no AI clarifications added to this market's description.
