-I woke up this morning weak and tired.
-I rarely ate today, I have lost my appetite.
-My stomach hurts, it feels like nausea.
-I am a 13 year old girl.
-My menstrual cycles are up to date, so there are no chances of being pregnant.
-I am pretty sure it is not PMS,(pre-menstrual syndrome) because usually I have slight cramps and irritability.
-I am looking for a diagnosis.
-I am slightly sweaty.
-I have a headache and I feel dizzy.

Thanks! :)

Are you sexually active? It could be anything from the flu to a virus. Have you told your parents?

Maybe you have a flu virus. We are not doctors and cannot tell you what's wrong. Tell your mom you're not feeling well.
