Second day after a night of drinking and i still feel bad like throwing up but i cant?

on saturday night i drank a lot . at te end of the nigt i felt like throwing up but i couldnt..it just wouldnt come out..i wanted it to so i can feel better but it just wouldnt. That same day earlier i had eaten very little only like half of a meal the whoke day so idk if it has something to do with that..Well on sunday i felt horrible the whole day with stomache pains..i tried to force myself to vomit but it just would not come out! Btw i also only ate one small meal sunday too. Well now it is monday..my stromache is not in pain but i have this feeling by my throat or lungs.. i think ...it just feels HORRIBLE . it feels so bad that i can't even sleeeep. I feel so weak and horrible idk what to do :( is this alcohol poisoning? why do i feel like this my friends that drank a lot like me feel totally fine so why am i like this-___-?
