Any one else ever had this happen to them?

I am just about always nauseous. Especially when it's time to eat breakfast, get up from a position, or am laying down for more than 10 minutes. I'm never hungry anymore and I don't sleep hardly as well as I used to.

This has never been a PMS symptom for me and it's been happening everyday since my period in the second week of July. I've tried tums and change in diet, exercise, going to the bathroom more but nothing seems to be helping. I did just start college and a long distance relationship with my boyfriend...could this be signs of stress? I've already had a period...sooo I have no idea what's going on.

What should I do?

Any advice?

Any one can relate ?

thank you guys so much for the advice. I'm going to see my doctor next week (only time available, it's flu season). Fingers crossed.
