I don't see how you could put prostitution on to that list given that it's unregulated and illegal in most counties, meaning rates of suicide amongst them couldn't be recorded. Especially when factoring in the amounts that are killed by pimps or punters, or die from alcohol and drug related issues, danger to prostitutes is far higher than any other 'occupation'. It's why police refer to them as high risk targets. Most violence against prostitutes isn't even reported, let alone recorded on a top ten list.

I've read interviews with 'Belle de Jour" who wrote secret diary of a call girl based on her own experiences. She readily admitted that she enjoyed her work but also made it clear she was a clear exception and that the vast majority of the girls she worked with (all high class escorts) hated what they did but needed the money to fund things like tuition fees and other such things. Most ended up self-medicating to get through what they had to force themselves to do.

My friend worked at a brothel for a year and had she not had a young son to support she wouldn't have done it. I sat with her crying her eyes out with humiliation over what she had had to force herself to do, but she continued to do it as she needed to provide for her son and she had no family to support her. She still hates herself for what she did and that was nearly 20 years ago. The psychological toll cannot be ignored, even to those who chose to do it.
