No, wait! A diagnosis, given that it's done properly, thoroughly, and verifiably holds true. What one 'feels' about the Dx is of no matter! This would be like a doctor, upon careful evaluation, tests, etc. saying to patient, "You have cancer in the form of __________, at Stage X." This is an objective, non-judgmental diagnosis based upon data, evidence.
If patient 'feels' that they instead have lupus, for instance, and willfully 'decide' they do not have cancer, they're just deluding themselves! What you 'feel' is irrelevant!
That being said, there are caveats: Such as, do you have real evidence, not revealed or articulated well, to state otherwise?
Yes, psychology is a 'soft science,' but still a GOOD diagnostician's evaluation is valid! Forget what you 'feel' or 'want' your Dx to be. It just is.
Much like when I'm collecting data; just get what you get! What I 'feel' about the data accumulated isn't a factor. Again, unless there's real evidence there's a procedural error, etc.
I suggest you get a 2nd opinion - just in case. If you truly think you've been overlooked, this is what a 2nd opinion is for. But do not obscure or 'sway' the facts - that's just wrong and is a disserve to you.
Whether or not you have AS is a moot point; you are what you are. I suppose then you'll need to accept/adjust accordingly. But you may not, at will, just arbitrarily change your Dx.
