awwww:( i know how you feel!
i've had this... its nothing to worry about:)
if you feel weak at the same time your feeling hungary then it could mean your blood sugar is low which means your not eating enough sweet stuff or consuming enough natural vitamins.
on the other hand, if your not feeling weak and just feeling hungay, then your either not eating enough or, your loosing more calories through exercising than your consuming and its causing you to become hungary. your body goes into starvation mode and begins to start eating away at lean muscle.
my advise to you is, start eating little and often!
either, start eating bigger portions or, the best thing you can do healthwise is, eat 4-6 medium to small meals a day. (not junk food) but lean meat/ fresh veg etc... and remember to inlude some fat as your body needs it:0 aspecially if your exercising regularly.
oh and, don't worry, i had this a few years ago and its actually very common;).
hope i helped!
