I shouldn't fret unduly; a diagnosis matters as much as you let it matter, it's only a word after all. If, after receiving the diagnosis, you don't think it fits you, just shrug it off. You don't have to tell friends you have it, aren't required to mention it in a job interview or apply for disability because of it, not doing anything about it isn't going to get you into any trouble, it just might make explaining any awkwardness in socialisation rather difficult. At any rate, long story short, if you don't like the label, then don't use it, it's not something to worry about.
