I don't believe MI is on the increase, not really. Its always been there but was ignored and not understood.
My grandmother was put in an asylum a few times, there were no meds then. Just a straight jacket.
The stressers are different thats all. Everyone is so materialistic now its all about the latest phone or car. So shallow.
Parents are the biggest influence on kids, for me I was not born depressed, but mother telling me how useless, stupid, fat and ugly I was didn't help much!
