Can you show me where it hurts :( ?!

On Sunday, the week before the last, I suddenly after having my launch, which was a meal from a famous American fast food restaurant, felt severe abdominal cramps, nausea, vomiting and diarrhea.
Although all my family members ate from the same meal order, and no one suffered anything, I thought that the food was contaminated and I had a transient gastroenteritis which, scientifically, should resolve with a few couple of hours.

So, you see my now swallowing as much as possible of Flagyl (Intestinal disinfectant) for 2 days but without any improvement. The constipation alternating with diarrhea continued, and the worst thing was the sever attacks of colics. Each of which persisted for one or two hours and didn't resolve even when I evacuated some of my bowel contents.

At that moment, I began to think differently, an older friend told me it might be irritable bowel syndrome (IBS) but I didn't believe too much in his opinion because I never thought the IBS is that sever!

On next Wednesday at midnight I had again an attack of that severe colics, I decided to visit a doctor.

I went to one who has a good reputation but his clinic was full of patients and the outside secretary told me that it was too late and the doctor could not accept anymore patients! I felt that I was a customer trying to buy something not a patients screaming from his pain! But I decided to go and not to beg such idiot.

I bought antispasmodic drug, returned back home and started to read about IBS in my books and on the internet just to find that it all describe the same symptoms and signs I had!

On Friday again I had an attack of the severe colics, I went to a doctor who is the father of my friend, Hisham. He inspected me and told me that I most likely had IBS. He requested some investigations regarding my stool, urine and blood and I added liver enzymes but all were negative, Nothing abnormal.

So, welcome the world of IBS!

Two days before, I phoned Dr. Mohamed hisham, he is a pediatrician but I owe him a lot of scientific respect. (He is my neighbor that's why I could call him). I explained to him what I had and he told me the same, I most likely had IBS, and gave me some advice.

I was astonished twice, the first because I never thought I'd have IBS at that young age, and the second was because I never thought that IBS could result in such severe colics.

"Ok, the world exploded in my bowel!", I told myself.

I called Dr. Ahmed Abdullah, who is a psychiatrist and a dear friend of mine as well, he asked me to take a mild antidepressant. "Here I am to antidepressants, the big ghost appears again!", I told myself. But Dr. Ahmed told me it is a mild antidepressant that psychiatrists prescribe as anti stress and anti anxiety.

Ok, I listened to him, although I began to recover at Saturday and recovered totally at Sunday. I started to take the drug.

However, yesterday when I was in the faculty I felt some sort of breathlessness and palpitation, I did not know why but "it's surely psychological", I spoke to my friend.
I thought it was because I was somewhat upset and stressed.
When I got up early today, Friday, I felt the same palpitation and breathlessness!
I don't know what I have but surely I'm sad for myself. I never thought that I could collapse whatever the pressures were.

I don't really understand myself and what's going on. I thought that I was adapting to my hell life and letting things go without much nervousness. But it seems that everything is just stored in my sub-consciousness and explodes whenever it wants.
I beg myself, can you show me where it hurts?!!
