Ski for 34 years now and cant 180

Hey everyone! Relatable thread?? lol. I have been skiing since i was 15, 34 years ago. I am 54!! I ski every year with my wife and son and used to with my friends. We used to eat opioids and ski in appalcahia but I never got better? Skiing is my favorite thing to do and has been for a while now but I still cant even 180. I'm so scared to. When i go in the ramp park all the good kids will laugh at me when I fall trying a 180 and it ruins my confidence... I have tried to learn 180 on normal ground but since my weight is big I cant seem to turn around fast enough. I need a big ramp to learn but am scared of all the bullies in the ramp area. PLZ HELP OR RELATE?? thanks
