Who do I go to?

So so first off I am a 22 yr F diagnosed pre-diabetic at 20 and my mom passed from complications with autoimmune type 1 diabetes and my dad is a type 2 and my grandparents have also had diabetes.

Okay so that the back ground info. The issue? I’ve been having blood sugar issues and I’ve gone to student health at my school and after blood testing everything is fine but for a while now I’ve been taking my blood sugar and I keep having random drops through out the day ranging from 85-65 and some small spikes after eating but most commonly I’ll have a drop two hours after eating instead of a spike or level.

This wouldn’t be odd were it not for 1. My blood test saying it’s fine and 2. Me being a pre for type 2.

So my question is who do I go to talk to about this?! Because my general healthcare at the school says my dizziness is just dehydration and has nothing to do with the fact that my blood sugar is randomly dropping. What is wrong with me. I need help
