Should we normalise a mental health excuse?

I just saw a post and I'd like to elaborate further about my thoughts on this.

I agree but dont. I DON'T want it normalized to the point where that's your every little excuse for stuff. Or people who are simply stressed over a test now think they have a whole anxiety disorder. I don't want it overplayed and taken as a 'cool new trend'.

We should want people to be more open to talk about their thoughts, feelings and emotions 100%, what we don't want is to further medicalize and pathologize our feelings, actions, and emotions. We don't want children to believe they are "mentally ill" and attempt to label their thoughts and feelings based on predetermined and arbitrary clusters of disorders that are still debated in the field of psychology.

What you're actually requesting is that mental ILL health should be normalized. Sure, people should be able to talk about their mental problems and difficulties. But the illness paradigm is often very misleading and unhelpful. 

This is not to say the psychological phenomena of depression does not exist, for example, but simply to critique calling it a disorder or illness and by extension assuming it is biological in nature. 

This is just my 2 cents as a psychology student that isn't too keen on the language of the "mental illness" pop culture movement. 

I'm so sorry to post this heavy topic in here. What do you think?
