I'm peeing a lot today. About 5 times.?

I'm just sitting in one spot doing homework for a couple hours. I rarely do this. So I drank like 4 bottles of beverages. 3 sweetened teas (400 ml bottles) and 1 bottle of water 500 ml. And after I pissed like 5 times. Why doesnt it go down after one piss but it takes like 5 trips to the toilet??? Like I would go and 15 minutes later, I need to go again. Seems a lil sketchy. Any problems with me? I am 17 years old. Active most of the time and my grandparents have diabetes lol. Can someone tell me what diabetes are. I know it has to do with blood in your sugar but what are the dangers of it? and do i might have it at this age?
