Do I have hypoglycemia? Should I see the doctor

I've had this practically my whole life. It has gotten to the point now where I feel like I need help. I am not diabetic though.

Sometimes whenever I don't have enough food or when I don't eat (starve), not just my stomach rumbles, my face becomes pale, I get a headache, lightheadedness, I may feel like wanting to throw up. People see my face looking pale and sick and ask if I am ok.

If I miss a meal the headache would back up really badly. I could be hunched on the ground holding my stomach.

Should I see a doctor? Is it worth going to? They may just tell me to eat enough food??

I thought it was normal until I was told that people don't get headaches when they starve
