Why is there / has there been sigma in the Church around mental health?

I know on paper  it isn’t different taking medication for mental health than physical health, but somehow the feelings around it don’t line up as a Christian- why the shame/ guilt around this?  Feelings of ‘failure ‘ etc? (32:51-48:27)

1.3) How do I be a good friend to people who are younger than me? I am not a mentor or anything, but there are younger people in my church that I want to be a positive person for. (48:30-1:01:56)
