i am not a doctor but wanted to respond to the nutritional aspects. some of the symptoms you list such as frequent urination are symtpoms of type 1 diabetes. i'm not saying you have it but it is worth being checked out. as for the dizzy feelings after sugar it's hard to say. i would aim to eat balanced meals with a protein healthy fat whole grains and fruits and vegetables. if you eat sugar do so after a balanced meal or snack. eating sugary foods on an empty stomach may contribute to the dizzy feelings. the best possible thing to do is get a physical that includes lab work to make sure everything is okay. in the meantime focus on taking care of yourself by eating well and getting sleep.
