Can you explain why these content creators struggle with mental health issues?

Most likely they struggle with self-esteem issues from the vanality of the field. Maybe they feel a lack of purpose in life, maybe they are used to being worshipped and the slight sign of rejection makes them depressed. Dunno, it could be many things. Maybe they want to love someone but it's hard given their job.

I'm just assuming things, I don't know what's going on with this specific content creator.
