Chest Discomfort/Anxiety

I have had chest pain for one year and a half now. I have had this pain EVERY single day since it has came. I have been in and out of doctors for this whole time and still have nothing. The tests Ive had done on me are EKG, CT SCAN, BLOOD WORK, STRESS TEST, and ECHO all for the heart. I have also had a ENDOSCOPY for the esophogus. All of these tests have come back normal. The chest pain is in the upper left part of my chest right over where the heart is located. It radiates to left side of neck, left shoulder and even into left arm, I know perfect description of a heart attack right? (sighs)
So here are some questions, Is it possible some of these test missed something? Can I have an ongoing heart problem slowly getting worse or is it even possible to have that kinda pain this long with out something happening already? Alcohol does make it worse thats the reason I had the ENDOSCOPY cause of it maybe being from ACID. I have to admit I am a VERY anxious person and have been for as long as I can remember. My mother told me it was anxiety even before I had any test done . I recently got some prescriptions for it cause Ive had every test and I feel like theres no other options. Been to cardiologist and gastroenterologist so what other choice do i really have. I feel like Id need the anxiety meds anyway cause I know I have it. I got some prozac for my every day dose and some zanax for the special occasions. (sorry if misspelled meds)
Im only in about 2 1/2 weeks of my prozac and my internal med doctor said it can take 4 to 6 weeks for it to start working.  Do you think these pains im getting EVERYDAY can really be from anxiety cause im sick of worrying and living my life around it. Im 20 years old, fit as can be and no history of heart problems that I know of in my family.
Please help if at all possible.
thank you.
