I, too, have been a bit more edgy than usual as of late. :/
Staying hydrated can help with both anxiety and Aunt Flow. Water is nice; green tea, if you can stomach it, is especially useful for calming. I also find peppermint tea to be calming, though peppermint is usually regarded as stimulating.
Sunlight and fresh air also reduce my anxiety, as does music, pacing, stimming (if you're prone to that), a creative task such as writing, drawing, or jewelry-making, and cognitive-behavioral exercises (such as the one found here, though the iPhone also has some pretty nifty CBT apps).
There's also sleeping twelve hours a day and neglecting reality altogether, though I would not recommend this approach if you have any obligations or hobbies to attend to.
Humor is said to be the best medicine. This might help with that: https://www.youtube.com/watch?v=fGNR5yCIOmw.
I hope you feel better soon!
