Hi. At your age if you do have diabetes it will be T1 not T2 and as others have said can come on quickly. Get a finger-prick test done at a pharmacy if you can or call 111 or go straight to A&E if you continue to feel unwell. In the meantime cut the carbs right down and drink lots of water until you can get a diagnosis. If you find an open pharmacy who won't do a finger-prick test then think about buying some Ketostix for testing ketones and even a meter and strips if they have them.
