Yes, there is a UBC facebook group! Here's the link: https://www.facebook.com/groups/ubcslpclass2022
There are also a few discussion posts in the graduate student community forum: https://community.grad.ubc.ca/
And for anybody feeling discouraged, agreed, don't give up! Speaking as somebody who wasn't accepted last year, application season rolls around again pretty quickly. My advice would be to reflect on those feelings, check in with yourself to see if this is still something you want, reach out to your support networks... then make a plan.
Also, take any advice (including mine) with a generous grain of salt! You know better than anybody else what you are capable of, and even so, you might surprise yourself.
Stay safe everyone!
