I would not suggest going on the pill, especially if you are having any doubts at all. I don't agree with the pill for the most part, as I do not feel that it is very healthy to stop ovulation, which is what it does.
I have always been a very strung out, stressed out person. I have not yet come up with a fool-proof solution, but I can tell you this:
Lavender is a calming scent...I know that sounds silly, but get yourself a lavender candle...you'll see.
Google "breathing techniques". These work, if you follow through and use them.
Make sure that you have some sort of "outlet"....such as writing, or singing, or dancing, running, painting, hunting, sports, etc....you get the idea. Good luck!
