When too much sex is a sign of mental illness

When Rachel was 18 she noticed her sex drive took a jump.

"It was literally all I could think about and if I wasn't having it then I would be doing something related to it, or watching it online," she told Hack.

"As I got a little bit older, it started getting to pretty much every day of the week and maybe two to three partners a week."

It wasn't long before it started taking a toll on her relationships and she decided she should look somewhere for help.

How one woman beat her mental illness by helping others

Following the birth of her first child, Jessica developed a problem with her thyroid gland that greatly exacerbated her pre-existing anxiety disorder.

"I've had anxiety my whole life," says the 36-year-old from Canberra, Australia. "The [thyroid] condition meant that my anxiety got out of control."

This was back in 2012, and Jessica decided to return to her civil service job sooner than originally planned, after she and her doctor agreed that getting back to doing the work she loved would keep her focused and hopefully mitigate her anxiety.
