I Think I Am Eating To Much In 1 Meal.

I think I am eating to much in 1 meal. I don't get to eat at work. Then I lay down and then my stomach starts getting bloated and it is soo painful. So 2 times I stuck my finger down my throat to try to throw up and relieve some stomach pain. Last night when I did that there was some blood in with the phlegm. I am afraid to eat. I took Imodium at 7:30am. I've had a bottle of water and a Ginger ale.
