How do you feel when your blood sugar is low?

Just asking for people’s personal stories, I am going to consult with a doctor soon.

Type 2 diabetes runs in my family. Every so often, I get this wave of extreme dizziness. It gradually gets worse, to the point I need to sit because I will be walking like I’m drunk, and I will start shaking/shivering. Then I will feel incredibly weak and hungry, even if I’ve just had a meal. I noticed if I eat something sugary, the feeling will usually go away. I am wondering if maybe it could be something related to my blood sugar, or if I’m simply overthinking it.
