Thanks for writing your query.
It seems that you are having some infection of the gastrointestinal tract and needs medical attention.
You should take antibiotic with antiamoebic and antacid
after getting yourself examined at the emergency department for hydration, blood pressure, pulse,etc.
You should try to maintain hydration by taking oral rehydration fluids. Diet should be light with less spice and oil.
You can get your stool examined to know the type of infection.
I hope this is helpful to you.
