fwiw, on the last point, my current plan is to do this kind of thing in local groups - I'm hoping to get funding for peer support in EA groups, basically to try and have this effect you speak of!
Me soon hopefully!
I'm currently still a student but graduate in June 2022 and hoping to go straight onto an (e.g.) EAIF fund doing peer support and mental health strategy input in EA Groups, or something more generally in the mental health x community building space.
Let me know if you'd like to chat more about this (anyone)! <3
