My dizziness(and other symptoms including: minor chest pain, minor pain in left arm, feeling like i am falling, heart palpations, hot flashes, sweating, feeling disoreinted, unalbe to see things clearly, ect..) lasts for my entire shift(4-8 hours, 5 days a week). My days are all the same-go to work then come home,watch tv, go to sleep, then repeat. Is there any way this could be anything besides anxiety?

A little history: smoke almost a pack a day, consume alcohol 4-5 times a week, take anti-depressants, have always worked in customer service, eptopic pregnancy, ruptured kidney, possible bolimea.

Please help! I am not myself and am feeling more helpless everyday.
