dizzy, shaky and weak

[Sola91]

I'm constantly shaky, dizzy, fatigue, weak, my vision sometimes becomes weird, I sometimes have trouble sleeping and my brain isn't working properly. When I eat I start shaking and I feel like everything inside me is running on incredible speed so I feel anxious and need to lay down. If I don't eat I get headaches and feel powerless. When I eat normal amount of food I feel the combination of these two, so now may days are about choosing between "which kind of sick do I want to be today?".
I've had a blood test which showed that I'm not diabetic and my hyperthyroid glands are working fine.
I'm 178 cm and 57,5 kilos and 17 years old.
I've had trouble with hypoglycemia, but never this severe, and my old tricks such as eating a candy bar or banana or simply eating whole wheat foods doesn't work : (. I eat pretty much everything (although I stay away from greasy foods and some steaks since I'm not a big meat fan) white and red meat, fish, vegetables, fruits, bread, corn and I always have either porridge or a toast for breakfast :|
I've tried pretty much everything! I've tried eating six times a day, I've tried eating two times a day, and the sad thing is that I actually feel physically better when I don't eat at all : ( (which I can't do because then I get hyperglycemic fits and become the third kind of sick... also then I can't concentrate on my homework).
this is causing me to miss out of school and worst of all enabling me to practice for my acting audition that I was supposed to take this December :(

ANY suggestions are well received : (

Less carbs more protein.  I don't think the all Atkins diet is healthy for but for someone with sugar issues you may want to eat foods that are low on the glycemic index.  Don't cut carbs entirely as that isn't a good idea, just try to replace some carbs with proteins. Look up the glycemic index in the internet and try eating more of the foods that are low on that chart.  Sweet potatoes are a carb but are actually low on the glycemic index so are actually really good for you.  If you eat white bread, switch to wheat.  Just a thought that may help you since it sounds like your levels are all over the place.

I meant to say I don't have hyperthyroid glands :Þ
