acid reflux maybe ? ugh

so ever since i was 19 years old i would eat and feel like foam coming up my throat and i would gag or throw up after i eat.... Idk what it is... til this day i'm 24 and i can't even eat in peace without me gagging or throwing up , don't get me wrong i'm not bullimic .., i weigh 125 pounds.. But i hate the feeling when i eat a lot or i eat and i gag .. NOT EVERYTIME THIS HAPPENS. but when i'm thinking about it or it happens.... I don't want to go to the doctor and get checked but if i want to eat better without me gagging then i have to do something about it.. Do you ladies think o have Acid reflux ? or something else ??? 😭😭
