I think you are being a bit dismissive of what is a widely accepted mental disability[1][2][3][4][5]. If you want to spout some nonsense about how you feel about the field, that's fine, but note that you are falling into the same category of people that don't believe in climate change because winter was "pretty cold". It just so turns out that the world is not all about you, and while it may be difficult to understand that this may be a real issue for some people, you shouldn't say that this is a substance abuse problem. To say that is at the very least ignorant.
