UK based friend of VI people here.
> my impairment isn't obvious, so they just think I'm a lazy teenager, and not VI.
I've seen this problem where someone still has the body language of a sighted person because they had normal sight as a youngster.
You can carry a symbol cane, or you can deliberately act blind (look past people not at them) or better you can tell them straight up "I have a visual impairment." or "My eyes aren't good", "Can you help me please" whilst thinking "I've done my bit explaining my disability now treat me with respect like everyone else gets." You are only asking for a little extra help, just enough for you to get by. (expletive deleted) if they don't show normal courtesy and respect.
> Should I take my cane to a rock concert?
Discuss this with your friend you're going to the concert with. They'll probably be surprised or even shocked at first but should quickly understand. They might be happy to keep an eye on you so you don't have the hassle of carrying a cane. The most awkward thing in a dark venue might be if they need to guide you to the toilets. Mention this beforehand and let them know you just might need watching while you find your own way there and back.
I don't know how people respond to canes in the US or how rowdy the concert will be, but consider that a cane might stop other people knocking into you or even get you escorted to the disabled viewing area or the front row. Or it could just be a hassle carrying it around when you should be having fun.
> Disney trip
Try the same approach as with the rock concert. If the teachers are competent professionals they will do a bit of research or get advice themselves. Make clear the limits of the help you need so they don't overcompensate.
This is a learning experience for them as well as for you. Tell the teachers "learning is fun" /s

> hates that the cane makes me "look blind".
Ouch! Try
$1But a good cane with the right training will give you that little bit of help and equalisation that makes you just as capable and independent as anyone else. In principle, it's no different than wearing spectacles, just less common.
> it's an
$1 that goes up to my nose
That sounds like it is too long, but I'm no expert. There are shorter canes which can fold compactly, I see ID / symbol canes that are waist high and mobility canes that come to your sternum and have a variety of tips depending on your needs and navigation technique. Training is essential to use these effectively.
$1 have an extensive range. Get advice so you can get on with your life.
> how do I stop people from "babysitting" me?
You will have to hone your political and diplomatic skills to the degree that you may end up as the first VI POTUS. As someone who has helped and guided various blind people, I have to consciously take care that I am not overcompensating or being overprotective. You will have to get used to being clear about what help you need and don't need because your helpers can't read your mind. You will have to be assertive about protecting your independence and personal space. E.g. don't let people take you by the arm, insist that they offer their arm and you hold onto them. They can *give* you help but they must not *take* control.
> my friends because they don't think I'm getting around as effectively as they are.
Either they adapt and take a more team oriented approach to activities or you will need to find activities where your visual impairment doesn't matter, e.g.
$1.
> I've never been given the opportunity to talk to an O&M person
I'm guessing you're USA from the jargon and language you use. The
$1 seems to have lots of useful resources. The sooner you get the advice, training and resources the sooner you can focus on your strengths and talents and get on with life.
