Feel like I’m going to pass out once a day

Hi all, I have been struggling and looking for help.

I feel like I have a great diet but still struggle with blood sugar symptoms.

A normal day for me consists of a high protein pancake with peanut butter. A 25g-30g protein shake with added collagen, fruit smoothie with added collagen. I fill my day with light snacks popcorn, cheese and nuts (or crackers), Greek yogurt with added protein powder, protein bars. I try to eat every 2 hours. I feel like I have a great diet, but I am mostly vegetarian due to preference.

And yet I still struggle with light headness that result in me seeking extreme blood sugar lifts like candy and other carbs. I feel like I am dying once a day. I recently ordered ovasitol + barberine because of some recommendations on here but does anyone have any other suggestions? I have an appointment with a PCOS friendly ob/gyn that was recommended to me. I have had my blood sugar tested and it has been fine, but I do not feel fine.

Thank you!
