21m It seems like my body is having a hard time tolerating alcohol

I’m a 21M. I started drinking at 17. Was drinking every weekend. And still am. I think I ruined myself so early because I was drinking new Amsterdam vodka straight from the bottle every weekend until it finally grossed me out. And I was drinking heavily to the point where I would throw up every time. When you’re that young there’s really no limit instilled in you. And I’d wake up fine the next day.

Now I have one beer/seltzer/shot of anything, I’m getting hot flushes, heart is racing, stomach is turning. My hangovers are super severe I get bad anxiety even if I barely drink anything. Would a break from alcohol help this? Or what else can I do? I can’t even drink just a little anymore.
