I’m scared

I didn’t know where to post this but I want ur opinions. I’m 16 and a month or 2 ago I went to my doctors to get BC and he took my blood work. I got a call back saying my sugar was a little high and I should reduce sugar/ carbs. I reduced it for a while but recently have been going out a lot lately and having more sugar. I get blood taken again tomorrow to see if it’s changed and I’m SO scared I have diabetes or something😩
