After having an intense 2 year DBT group in my when I was 60, I can honestly say I wish those skills had been available to learn back in the late 1960's when I was in high school. I had managed to learn many if the skills by dumb luck but so many others would have been useful through the rough times of my life.

I had dysfunctional parents who had no useful skills themselves to teach & no mentors around so I winged it & messed up my daughter in totally different ways due to lack of skills & taught her differently but still not useful skills she needed. Just passed on different dysfunctions each generation trying hard to not be like the previous one.

Not sure mental health classes would have helped. I had psycholigy in college while getting my technical degree & I still had no idea I was having a breakdown when it hit in my 40's...knowing stuff intellectually is a lot different than understanding it practically
