I think it’s also become much more acceptable to seek help for mental issues. When I look back at my school days there were a lot of people who had mental problems. Including me. But there was nowhere to go
Bingo. I personally knew of awful situations among classmates (not to speak of my own issues) that they never seeked help for, and I'm sure thats just a tiny fraction of what was going on.
Maybe there was somewhere to go, but therapy and counselors were not part of the culture.
