Don't know how badly its affecting you, but about Feb of 2008, work stress culminated in a series of panic attacks for me. I had moderate to severe anxiety 24/7 for months, occasional panic attacks, and for about 9 months I couldn't have a drop of alcohol without experiencing high anxiety.
Tried meds - BAD IDEA. Took 2 doses and quit.
People react to stress in different ways, and maybe you'll never experience this stuff, but if you do, it can be beat.
It helps to focus on the worst possible scenarios. Speaking as the sole breadwinner for my family who has just been laid off, you're job is not the most important thing in life. You are probably not one step away from homelessness.
I drank a lot of chamomile tea, you might try that. Don't drink much during the day, though, I found that it made me kind of spacey and forgetful.
People don't understand how serious anxiety is for the sufferer. If you are having it, find someone who's been there to talk to about it.
