Any diabetics or prediabetics need advice

So I been worried about being prediabetic if not becoming diabetic. It runs in my family very badly out of my mom n her siblings out of the 6. 4 of them are diabetic. I already had an aunt die by the age of 46 because of the things being a diabetic can cause. I ate about 5 hours ago and I took my blood sugar and it was at 122. Is this something I need to be worried about. I'm getting evaluated for pcos in Jan and the more I look it up part of it can be caused by being prediabetic. I see how hard it is on my mom and her sisters and now one of my cousins found out at 23 that she has type 1 just like her mom and our aunts
