Try to see the big picture. Don't sweat the small stuff, prioritize, make a list and take one thing at a time, try to avoid multitasking, delegate, get help, don't let pride cause you to take on more than you should handle.
Tell your self that you will stay calm, cool and collective, because you will make better decisions. If someone ticks you off, do not address it until you have thought about how the incident fits into the big picture. It might not be worth dealing with, sometimes it is better to be wronged and move on to the more important things. Discuss things on your mind with those who love you. Don't keep stuff bottled up because if an unforeseen incident comes up, you could blow if you don't do things to dampen the impact of your rocky week.
Do not procrastinate, it could pile up that could cause even more anxiety.
Take care of Business with a good attitude, even if it's forced, compliment people, send good vibes and people will send them back to you and before you know it you'll feel better and motivated under the circumstances, be an optimist and SMILE
