what does it mean if I gag and feel sick at the littlest smells and sights?

[Bgsoccergrl]

I am 19 years old and ever since I was like 16 I always had stomach aches. I tried not eating or drinking dairy products to rule out being lactose intolerant. That didn't help. The older I get, I gag at the littlest things. Like I will walk into work (mcdonalds) and instantly feel nauseous at the smell of the food. This has never been an issue for the two years I worked there. I can think about something that has made me nauseous in the past and gag and dry heave. I don't have one day when my stomach isn't unsettled. I never really thought much of it until now. I always thought it was maybe lack of sleep or something I ate. But after starting to eat healthier and paying attention to how often it actually happens, I am starting to grow a concern. Please, if anyone else has this issue or had this issue, tell me what might help or what it might be.
