I'm not going to be much help. I deal with stress by fleeing from it/ignoring it.
A few years ago I went to my doctor to discuss some health concerns relating to my heart rhythm, blood sugar levels, and the fat accumulating around my midsection - this despite eating a "healthy diet" (CW) and exercising regularly. She told me they were telltale signs of stress and suggested I eliminate as much stress from my life as I could. And I did - I quit my job the next day. That was a few years ago, but since then I've done everything I can to eliminate stress from my life.
I got a great job that requires me to only put in my 8:30-4:30. I am not tied to a BlackBerry and I don't bring work home with me. The company I work for is awesome, fun, laid back and even though I've set myself up in this cushy rut that I may never advance out of, I really love my job. I don't have a lot of drive anymore to scale a corporate ladder. I earn a decent salary and I love what I do; I could earn more at one of the big oil companies downtown - WAY more - but then I'd be doing work that means nothing to me, I'd be BlackBerried, I'd have a crappy downtown commute every day, a dress code... nuh-uh. I believe life is too short to sell oneself out for the sake of scaling an imaginary ladder.
Another big thing I did was get rid of the busyness. Being "soooooo busy" is like a badge of honour in our society. Having 75 things on the go at any given time - it makes us feel important. I am proud to proclaim that I am not busy. I have my days where I'm triple booked, but they are rare and accidental. I spend a good amount of time unwinding, reading, partaking in hobbies and relaxing, and I don't apologize for it. I was SOOOOO BUSY all the way through my twenties and early 30s - working no less than 3 job plus scaling corporate ladders plus going to school plus renovating a crappy house and working on a crappy relationship... It's chill time now. I'm doing it for my health.
I think more people should calm down, chill out and realize that their life will never be defined by how busy and stressed they were.
