Major anxiety, panic, fatigue- Quick relief???????

I am having the above symptoms all of a sudden and was wondering if there is something that I could take at least for the recurring anxiety/panic attacks? Is there a tea or something I could buy like chamomile tea? It is 10 pm here in southern california and no health food stores are open.
I haven't been doing the right things lately, been working a lot and have a little stress in my life due to marital issue but I know what I need to do to solve these things, I just need some immediate help with the anxiety/panic attacks then I can work on the fatigue, stress and diet issues. I have isocort but want to take a cortisol saliva test before I take it. Maca has helped in the past but I haven't taken it consistantly but will start again.
Thanks,
Robbie
