Thanks for this! It means a lot. It can be a little discouraging to hear criticisms when you've put a lot of thought and time into something that you hope can help people.
But I fully understand and appreciate the comments made by other posters.
I have put it back online with a disclaimer that must be acknowledged, and pointed out this is a research app not a substitute for therapy.
I hope that does enough to mitigate some of the risks, whilst allowing me to continue to work at making this a safer and more valuable resource. Whenever that may be, or not :)
