I've had my biggest burnout yet last summer, just didn't see the point of going somewhere for an hour, and my thinking was 'what is a 1hour booking going to change in my life anyway'. I got very lazy but not really depressed. i decided it was ok to be a bit lazy in the summer, and I actually still feel a bit lazy, but to be honest my new attitude has done me really well. I used to chase every booking and had sleepless nights if I didn't meet my targets, but now I am totally zen, and have time for new hobbies, two lovers, massages, coffees with friends, weekends away, and I only take bookings that I am 100% comfortable with, I don't ever work late anymore, and I've finally found a good balance I hope!
So don't get too depressed about not wanting to work, especially in a horrible month as February! do some nice things, work as much or as little as you need to keep your head above the water and slowly get back om track!
