I'm a college student 19 years old and I've been eating sweets lately my mom's side has diabetes. Do I have diabetes right now? I'm really afraid

Why. Eating sweats will not give you diabetes (old wives tale).If you are eating continuously and losing weight, feel nauseated most of the time and pee almost continuously you may have type 1 DM and need to see a doc immediately. If you feel fine, schedule a visit at your convenience and discuss your worries.
Diabetes. Don't be afraid. Please see a doctor on campus and ask to have your blood sugar checked. If OK, relax. If blood sugar is high you will be referred to either a Primary doctor or an Endocrinologist. More than likely you do not have diabetes.
