Constant gagging reflex, nausea, no vomiting.

Hey guys, I'm a 15 year old girl in good health, with no past health problems. My family members do not suffer of any illnesses either.
I have recently (for the past 1 or 2 weeks) been constantly having a gagging reflex, for no clear reason whatsoever. I have also been feeling very nauseous, especially after eating.
I thought maybe this was due to the fact that sometimes I did not eat for whole days, or eat just one meal a day. My BMI is normal and I am not over or underweight.

The other day, I was in the shower, when I opened up a bottle of shampoo (the same shampoo I have been using and have used before for a long time) when I suddenly gagged and coughed and felt like I was literally going to throw up, but nothing came out. I keep getting this feeling all the time, especially after eating, or when I think about life, war and things like this. I have a weird feeling in my throat along with nausea all the time and I feel very miserable.
Could this gagging feeling have something to do with my eating habits or stress or anything?
I'm very confused and this feeling is starting to really, really bother me, even after only about 2 weeks, as it is a feeling that is constantly there.

I would be very glad if anyone could help/give me information.
Thanks in advance.

Hi,
Nausea could be due to GERD, ulcer disease, liver disease and even anxiety.
If the symptom is persisting, then you may have to undergo tests for the above mentioned disease.
