URGENT - can you reply in next 30 minutes? please?

SOrry for the title and urgency but I just really need some advice. Maybe I should call NAS. I don't know. Anyway I am going to open a new bank account today, and I don't know if  I should tell them about my diagnosis. I now have the letter confirming diagnosis - do I tell? Or not? Is there something you can get that says you have ASD but doesn't include all the personal stuff about hobbies and interests and difficulties with relationships and other things? Can I get something like a statement to show to banks?

But anyway the real question is do I tell the bank or not?
