Business meeting symptoms and conditions

I was on Sulfamethoxazole-1pill 2x day/ 7 days- for an intestinal infection. I started on Monday and by Wednesday I developed abdominal pain on my left side, Thursday I was feeling so tired and not as alert as I should have been and I had panic and anxiety attacks while in a business meeting; my heart was beating through my chest even hours after the meeting had ended. Friday I realized I had developed a burning and itching sensation in the vagina area and that I had redness and white bumps all around it. Thanks to MONISTAT CREAM which I used for 2 days- twice a day- to help with the itch. On Saturday ( 3 pills away from finishing the treatment) after my husband found this web site and started telling me that all that had happened to me this past week were side effects retaled to Sulfamethoxazole, I stopped. I have been driking lots of water to help clear my system faster and today (4 days later) I am felling much better and my symptoms are starting to clear out.

I accidentally(thank God) stumbled to this site after typing in a search for : viral infection that causes dizziness,racing heart,lump in throat. Up popped this!!! I was horrified but at the same time relieved. I am 35 yrs old and for the past 2 weeks I have been suffering from panic attacks,dizziness,uncontrollable hunger,constant thirst,tingling in my lower arms and hands.
I've been on Yasmin for a year now and am just now noticing these potent symptoms. I was in a restaurant in a business meeting 2 weeks ago. I suddenly felt hot,sweaty and extremely dizzy. Scared me to death!!
I've since been to my doctor 2 x's this past week. She's prescribed Omnicef,Zithromax,Augmentin XR under the assumption I had a sinus infection or ear infection causing these symptoms.
I took my last pill of Yasmin 6 days ago for my new cycle,and coincidently called my OB/GYN and complained about how expensive Yasmin is. She switched me to Estrostep. Is Estrostep better,the same or worse than Yasmin?? I still feel like a bus hit me,head is light and dizzy,nervous,panic attacks have spread out but not left completely,and hunger has slowed down. Am I getting better? Do I still need to go back to the doctor? Can I be fixed? Do I need a supplement? I need to relax so I can mother my 2 children and function in my daily life. any suggestions?
I thank God I accidentally found this site. Although I don't think it WAS an accident....HE answers prayers in the most awesome ways.
