HELP!!

So i went to the doctors yesterday and he told me that i might have diabetes. He said that my pee is fine (i have keytones but i didnt really eat anything in the morning except for beans and havent ate in the past 12 hours) I’m extremely worried and depressed. My family said that it’s probably my anemia and that if there was actually something wrong, he would’ve found it at the appointment. My blood test is Saturday and i feel so anxious and down and have been crying alot. I have most symptoms like thirsty , tongue hurting on the sides, dizzy and lightheadedness and feet and hands are sometimes cold numb. My mouth is especially thirsty and i drink a lot of water though.For any info, im 15 and my dad has type 1 diabetes. Please help me!
