A truly Anonymous talk therapy service
Your idea does already exist on my first google search: https://freeonlinetherapy.org/
I'm sure you could explore your options -- we are currently living in world where the pandemic has caused a majority of the world to be in quarantine lockdown in isolation. There's a reason that solitary confinement was ruled as inhumane. Yet, here we all are... some of us are lucky or not so lucky to be locked in a house day in and day out with our families while others are lucky or not so lucky to be in a small apartment by themselves day in and day out with just a virtual connection.
I'd say go for it, but do your research beforehand. Just know that there are heaps of free services out there including phone lines people can call and talk to someone for free. And in society we currently live in... many people aren't looking to pay any money for such a service.
That's just my thoughts.
