heavy drinker of two years, is it safe to quit cold turkey?

I’m 21F, 120 lbs 5’4 and have averaged about 4-7 drinks a night for the past two years. i’m getting sick of all the anxiety it is causing me. i am an active person and go to the gym regularly. my RHR used to be in the low 60s. these days it’s 80-90. i just want to quit cold turkey but i’m not sure if it’s medically safe. i appreciate any advice! thank you guys
