Question

How to approach this task? From which side to dig?

Answer 1

First of all, you need to talk to a couple of psychiatrists. Or, which is easier, accept the emails of the mentally ill for processing and identify patterns.
Well, the identification of a mental state and a mental deviation are two different things.
For example, a person can be angry or even angry and write a bunch of exclamation marks. Or he does not have enough computer literacy to turn off caps lock and he will write all the text in capital letters.
PS Do not forget the joke that every person is mentally ill in one way or another, a specific patient is the one who is on fire))))
