Growing a thicker skin from bullies

[UnashamedAndAshamed]

Ever since the events of November last year, the bullies have been out in force. I'd been bullied all my childhood, and now all the trolls I've had to battle are bringing those memories back. I can still work at my job, but once that's over and I try to do anything fun, those trolls are back in my head again and all I can think about is curling up in bed. Do you have any recommendation for how to get immune from recent bullying and also get past my childhood? I'm 42 and feel like this has gone on long enough.
