"It only seems if I think about it’s there and if I stress about it it gets what worse." - I think you answered your own question. It sounds like a lot of anxiety to me.
Herpes symptoms wouldn't appear for at least 2 days at the very earliest. The average is 4 days, but can be up to 20 days.
I have to say that anxiety over oral herpes is kind of pointless. Over half of the adult population has it, and if this isn't the first person you've kissed, you've likely been exposed before. Chances are good that your parents, aunts, uncles, grandparents, etc., have it. If you freak every time you kiss someone, you're going to spend a lot of time freaking.
Don't kiss anyone with a visible sore, and maybe during cold and flu season, don't make out with random girls, especially if you haven't had a flu shot. The flu will make you a lot sicker than herpes will.
