@Beatle1,
Ah, then there's an enormous physical safety issue there.
I'm female. I am
not going to a private place with a stranger, and I am not unloading my dirty linen (intimate personal problems) in public.
There's also a massive issue with untrained people.
What if the person who wants to talk is suicidal? You've just created a burden for the listener. Untrained strangers will do everything from tell someone the wrong things (
oh, you'll grow out of being gay!) to telling them to jump. Don't say that doesn't happen. Someone gets on top of a building and says they want to die, and there are always people who will tell them to go ahead.
There will also be so-called listeners who will use the moment as a prime opportunity to proselytize for their religion.
Others will use it as a dandy opportunity to rape or roofie someone.
Also, psychiatry (not psychology) is a medical profession and the people doing it have MD degrees. Those people need malpractice insurance, but they get insured because they are skilled at what they do and they have defenses.
Your listeners can't prescribe medicine (unless they are doctors for some other reason, and doctors wouldn't do this), but if they open up their bags and hand over prescription drugs (
here, I've got some leftover Zoloft. Want some?), they may be considered to be practicing medicine without a license.
I hope your new business model has a healthy budget for insurance—which you will probably not be able to get from a regular provider.
