Hi mak,
Welcome to Thalpal!
Your symptoms are that of any other thal minor, no wonders. I could give you some advice regarding supplements which might boost your metabolism, activity levels and may help you lead an active and healthier life ahead.
Natural Vitamin E (400 IU daily), B-Complex (B1,B6,B12), Vitamin D, Folic Acid (400 mcg) are some standard supplements.
Also, have you got your D levels checked? Low D levels often lead to fatigue and stress. Above 35 levels of D is advised.
You will find some great advise here on Thalpal, check out Diet/Nutrients/Supplements section, you'll find many related topics.
Regarding food, avoid junk food, especially avoid empty calories. Make sure your diet is rich in nutritious food. Also try to consume anywhere between 500-1000mg of Vitamin C either through diet or supplements. Some natural sources of vitamin C rich foods are oranges, lemon, lime, etc. Vitamin C also helps you fight with fatigue and helps absorb iron from your food.
Best,
-P.
