I think i have a hole in my stomach...?

You've possibly damaged the lining of your stomach. Almost like when the part of the egg of a boiled egg is peeled off, and the inside of the egg becomes fragile. It will start to hurt more over the next few days since the acid in your stomach eats away slowly at the lining of your stomach. I suggest you see a doctor, and they will give you medication until you recover. They will probably suggest you not to eat certain foods. My friend, who tore part of her stomach lining, took weeks to recover, and this might apply to you. Her drugs also made it hard to digest and she was unable to bend down... Good luck... =)
