Could I Have Diabetes?

I noticed i few symptoms that i had which related to type one diabetes that just started 3-4 days ago, but it is starting to worry me.. the symptoms are Type 1 Diabetes Frequent urination --- not too much more, but sometimes i just randomly have to go really badly Unusual thirst--- Usually in the morning i never drink anything, but lately i have been so thirsty that i have to, even during the day i am more thirsty Extreme hunger--- not exactly more hunger that ive noticed, but in the nights i tend to get hungry and munch on junk foods Fatigue- I'm thinking this could also be possible to the fact that I have slept no more than 6 hrs a day for the past week I am only 14 years old, and for the past month i have been eating very unhealthy, I am 5-8 and weigh 170 lb, however i have been exercising for past two weeks ( i am on sports team) can this be a case of diabetes? b/c my dad is also diabetic.. and im starting to get worried... how can i prevent this if its developing..?
