I feel like your example shows the inverse of what you want. SSRI are actually great at helping the person develop healthy mechanisms (compared to GLP-1s), because they reduce the mood swings & negative thoughts, allowing the person to be more productive & be more involved in their therapy, in reading, journaling, doing sports, etc. It's just that it might take two or three years and not months, which is fine because SSRI also have much more limited side effects compared to GLP-1s.

GLP-1s don't do that directly.. but at least they might help people move more, and give them confidence to do more for their health instead of seeing it as a lost cause.
