guilty as charged

We have been dealing with Ella's intestinal issues for about two months now. We have seen a doctor three times and the last time a specialist was consulted. She took a heavy dose of penicillin to clear up what was thought to be an infection of the colon. i was instructed to call the specialist if she wasn't 100 % better. She was better, but no 100% so I called an left a message. the nurse called me back 2 days later and shamed me into giving up her appointment spot. "there are many sick kids that have been waiting to get into Dr. GI God. She sounds better, they need the spot." So against my gut feelings and twisting my arm I gave it up. A day after the phone call, her symptoms have returned. I am so ticked at the nurse and at myself. I should have stood my ground. My kiddo is one of the sick ones that needs to get in now. She is not in pain or anything, but things are still not normal and I have exhausted all of my resources. She has done tests, we have changed her diet ect. I don't know what else to do. I guess i will have to try and get her into Dr. GI God on Monday. This time I will be the one twisting arms and dolling out the guilt trip!
