Unfortunately I have to agree with the parent, it does seem to be true.
In my own experience: my niece never mentioned depression until she saw videos about it on TikTok. Then she was always moody, and constantly stating "I'm depressed, but therapy is expensive. Can you give me money? Don't you feel bad for me?"
I see people walking around with T-shirts advertising they suffer from depression.
I don't know if social media and exposure has brought the correct view of mental illness to light.
