You’re in good for you, now you’re in a GDN submarine you have to tune out all the background noise and listen for the noise that matters, all of the rest is muted.
I’m not a physiologist but you will find jealous mean hateful people that just can’t stand you being successful on the s/m. Be extra careful and don’t get sucked into Psss I know something you don’t.
And sometimes you lose and sometimes you win.
All the best with GDN
