What has been said about exercise is good, though I would say to get into the habit of doing it nearly every day (this is something I should be doing, and am not

). How you look at the situation can also really effect your anxiety levels. Try not to worry about what
may happen with your job in the future. Make plans to do something you enjoy after work (even if it's just chatting with a friend

) and when your anxiety starts to go up remind yourself that it's only a few hours until you get to do that. And always remember that this crappy situation is not forever.
Finally, no job is worth sacrificing your mental health for. Truly, it's not. If it really becomes too much stress for you to handle, please, please quit before it pushes you over the edge. Look at it this way: If you destabilize you're going to lose your job anyway, and then you won't be able to look for another one! I know how bad it feels to admit work is too much--I just had to do that myself. But I
guarantee your family would rather lose your income than lose you.

I so hope work is going better for you today.
