This really comes down to weather you want to live or die. I'm a 25 year old woman who was forced to choose between drinking and everything else early in life. In the beginning I couldn't see a life without alcohol, and the first year sober was confusing and painful because of all the feelings I had been numbing with alcohol. But it gets better.
You are young and if you stop drinking now you have a lot of time ahead of you to heal and to build a new life. If you keep drinking you will only get lower and lower. I hope you find a reason to stop drinking.
