When an irrational fear prevents you from doing something, that's basically a definition of psychiatric disorder.

It doesn't matter if you have no great desire to do it in the first place. If someone thinks an activity isn't useful then that can mitigate a phobia, but it's orthogonal to the actual existence or not of a phobia.

Nobody is judging you for your preferences. "won't" and "can't" are different things.

So if you're calling the overuse of chemicals bullshit, fine. But don't call a clear diagnosis bullshit.
