Help!!!! I am so tired of this happening!?

Okay so whenever i eat my stomach hurts and then i get hiccups and these aren't the ind of hiccups that go away if you drink water/ get scared/ ect. these are evil hiccups that stay from a few minutes to hours... like if i eat a granola bar, hiccups for like 5 minutes. anyways Then randomly in the day i get horrible stomach cramps and if i curl into a ball or put my knees up to my stomach it makes it to where i feel like i am about to puke and those come and go but when i have one its like on for 30 minutes off for an hour then on for and hour or two. and when i press on my diaphragm i have sharp pains and i also get sharp pains in my appendix area... i don't know what it is and i would really like to know... no its not i eat to fast cause once it took me like 2 hours to finish my meal and it still happened... please if you know anything or have a guess or suggestions.... leave them below... thanks
