I've heard some people say that it's not worth it, since those kinds of things "never go away", but she means a lot to me. I feel that mental illness is only one aspect of such a person, with pluses and minuses (one such plus being that it makes her a stronger person).
A huge number of people at my school have Asburger's, and many are on meds for it. I've seen a lot of them become much more stable and balanced people, mostly because of increased exposure to people like them as well as normal people.
Personally, I've found I've developed a very high tolerance to people with personality quirks.
