>PS. there are many other treatments that doctors will give you before reaching for the big guns; those can be very effective too.

This part can sometimes be difficult if you are in crisis. There’s lots of other options like you mention but they tend to take longer to see an effect. Ketamine can be very immediate in that regard. I remember it being like a light switch and thinking “wow this is how others must feel!”. And just seeing, even once, that it is at least chemically possible for your own brain to work/think like that can be very inspiring and hopeful esp when it feels like it hadn’t been worked correctly for a long time (or ever)
