I Was Pretty Upset Yesterday So I Ate 3 Spoonfulls

I was pretty upset yesterday so i ate 3 spoonfulls of peanut butter and two cadberry eggs. Then about 2 or 3 hours later i ate veggie soup and drank mountain dew. my stomach hurt while eating so i didnt finish the soup. My stomach has never hurt after eating any of these things before so i dont know what to do or eat. Last night i ate two pepdo tablets and used a heating pad all night and it hasnt really helped and ive gone to the bathroom a few times. i didnt get more than an hour of sleep. I drank some water at 4 am and it hurt so i put the heating pad back on and layed down again. i want to eat because its been almost 24 hours since i have but im scared to and dont know what to eat. Please help!!
