I almost had a major burn out recently (pulled myself back, thank god.) The only thing I find damaging is the stigma attached to the job. I was recently run out of my own town, paint thrown at me, beheaded xmas snowman, disowned by family etc. So It does get me down sometimes to know that people view sex workers as either Whores or victims, but I'm not sure what we can do to change such a deeply rooted view. I've had civvie jobs and hated them!
Except one major burn out where I had to take a office job (never again until I have my house) I really do love this job, I do it partly for the huge financial gains, and think any of us who said we didn't would just be kidding ourselves, but also because aside from my rants about timewasters and getting lonely sometimes I really do love the job and the sort of lifestyle being self employed gives me.
At the end of the day, its been 6years, I wouldn't be in any other line of work because I love it!
