Yeah. It's the difference between the friend who is depressed but is working every day toward getting better even when that sucks, by going to therapy visits, exercising, finding meds that work with a low side-effect profile ... and the person who is depressed and just wallowing, skipping psych visits because "I just can't get out of bed" and making every interaction with "friends" revolve around their needs without ever sucking it up for a few hours and dealing with their own shit instead of making someone else wait on them.
One of these people, you'd tell a friend to stick around with, because they sound like they're making a huge effort and trying to maintain their end of a friendship. You'd give that person a lot of leeway, even if they had occasional slip-ups where they went into full-on "can't leave the house" mode for a little while, because it's obvious they're doing what they can. The other is existing in a state of learned helplessness and feels entitled to one-way friendships that exist only to help them maintain the emotional regulation they never learned to have on their own.
If Nora did certain key things that made it seem like she gave the slightest actual fuck about improving her mental health, I'd be the first to give her credit for it and be happy for her. But she clearly doesn't. Someone who wants to improve their mental health doesn't spend time on social media nervously checking their mentions. Her therapist would tell her not to, and if she wanted to improve her mental health, she'd use her computer literacy to get a browser extension to block Twitter. She'd get outside more and decide her gender issues didn't matter until she was mentally healthy in other ways, so that she could understand more clearly what it is she wants to be. She'd figure out a diet and exercise plan that made her feel better. She has support and resources for any or all of these decisions.
The more I see of Nora, the more I'm convinced that her "mental illnesses" are a cover for laziness and lack of personal virtues.
