Anxiety transcends a normal thing and enters mental illness when it becomes pervasive and unreasonable. My anxiety about having used a wrong word in a conversation I had last year is unreasonable. My constant feeling of dread is unreasonable because I'm not constantly in a situation that should inspire dread. Mental illness is really hard to define properly- there always seems to be something left out, or something that's implied to be illness when it isn't.
Honestly, I feel like the discussion has been derailed a bit- we're focusing on defining a very vague thing that we don't understand yet. I can't offer answers at to how we should define mental illness because that's a question that would take years to answer. And it seems like one of those questions no one will ever agree on, either. As a utilitarian, I think mental illness is a thinking pattern that causes unhappiness or harm over a period of time, or that blocks someone from being able to view the world realistically. Someone else might have a different set of values that has an entirely different set of "bad thinking patterns."
But people ARE suffering, we know that there ARE diseased thinking patterns, and we know that people want help. Maybe "mental illness" is a bad frame, but at the moment, do we really have another to work with? I don't think so, which is why I think that this is an important question. All of the answers we're getting are mysterious, and thus not answers.
Yes, I want to do change work, and I think that it's impossible to do anything if we refuse to start helping because we don't have a good frame yet. Sometimes you have to explore a problem for a while to even start to figure it out. We have an extremely flawed and basic understanding, and saying, "well, what can we do then?" is like throwing out a hypothesis because of one inconclusive experiment.

If the thought of asking out a woman for a date raises anxiety in me I don't care at all whether or not that's "reasonable" or "normal". It's a trigger that I don't want to have regardless of whether it's classified as a mental illness.

Yes. I have multiple different one's.

For a site extremely focused on fixing bad thinking patterns, I've noticed a bizarre lack of discussion here. Considering the high correlation between intelligence and mental illness, you'd think it would be a bigger topic.
I personally suffer from Generalized Anxiety Disorder and a very tame panic disorder. Most of this is focused on financial and academic things, but I will also get panicky about social interaction, responsibilities, and things that happened in the past that seriously shouldn't bother me. I have an almost amusing response to anxiety that is basically my brain panicking and telling me to go hide under my desk.
I know lukeprog and Alicorn managed to fight off a good deal of their issues in this area and wrote up how, but I don't think enough has been done. They mostly dealt with depression. What about rational schizophrenics and phobics and bipolar people? It's difficult to find anxiety advice that goes beyond "do yoga while watching the sunrise!" Pop psych isn't very helpful. I think LessWrong could be. What's mental illness but a wrongness in the head?
Mental illness seems to be worse to intelligent people than your typical biases, honestly. Hiding under my desk is even less useful than, say, appealing to authority during an argument. At least the latter has the potential to be useful. I know it's limiting me, and starting cycles of avoidance, and so much more. And my mental illness isn't even that bad! Trying to be rational and successful when schizophrenic sounds like a Sisyphusian nightmare.
I'm not fighting my difficulties nearly well enough to feel qualified to author my own posts. Hearing from people who are managing is more likely to help. If nothing else, maybe a Rational Support Group would be a lot of fun.
