New to IBS

Hi, Im 25 years old and was just told by my doctor that I have IBS. He gave me medication and sent me on my way. However, the medication did not work, and based on all the info that I have read about IBS.....its just not that easy to solve..take a pill and u'll be fine. HA! My symptoms are actually way worse! So I am getting a new doctor, but in the meantime, I am trying to figure out other ways to deal. I cant figure out any trigger foods.....I have taken certain things that I thought bothered me out of my diet and then re-introduced them again a few days later and didnt have the same result. So I dont think its certain foods that trigger my "sickness". I suffer terrible stomache pains, very sharp pains that are so bad that I get really hot and almost dizzy like I am going to pass out. Bad diarreah......uugghhhh......and the urgency to go. I dont leave my house...unless its to go to work. And somethimes I dont even make it there. I wake up in the morning and the first thing I feel is those pains in my stomache, and thats how the rest of day is. I am starting to get scared b/c it just keeps on getting worse and worse and I have no control. I am not an emotional person and I dont like to cry, and I balled my eyes out the past few days b/c I feel so alone and out of luck with the situation. I am at a loss of what to do as I wait for the day of my doctor appointment to come....
