That's one of the only real downsides of apparent intelligence that I've seen: people in positions which exist to be supportive tend to assume you don't actually need their help.
Which, comparatively, might be true. But just because someone else needs more help doesn't mean it wouldn't be welcome.
Parents, teachers, advisors, supervisors, they just let you figure it out because they know you can, and they need to focus on those who can't. I had a career coach once tell me I didn't need to worry about finding a job, smart people always find work.
If you've never needed to ask for help before, this can really cause problems when you finally do.
