I've stopped eating something which turns out i'm actually allowed to eat? Soo Confused.?

you are looking for a reason to break a promise and trying to justify it using the quran. There was an american singer in the 70's named cat stevens. While nearly at deaths door, he made a promise to allah. That if allah saved him he would devote the rest of his life to being a good muslim and give up everything haram. Today he is known as Yousef Islam, and although he is still singing he now sings songs about islam, and spend a great deal of his time teaching islam. He gave up the , drugs and rock and roll. I think you can give up a few things, you made the promise, now stick to it!!
