Hi purple and welcome to the site
Yes you definitely are smart for someone so young. Now that you have seen that the good days are over with the booze there is no going back. It's a big decision to quit but your life is going to be so much better for it.
As you have found quitting and staying quit are two different things. I would also strongly urge you to go to some AA meetings. You need the face to face support of people who know exactly what you are going through......you will probably even make some new friends. If you can try more than one meeting if there are too many of us older ones there (you're fortunate you found out young that you need to quit, many of us spent many years trying to work that out)
Once you have that support you will find it easier to 'ignore' comments from friends and family which are unsupportive and could ultimately lead you back to drinking.
We also offer a solution in AA for living a joyful, sober life. Keep an open mind and look for similarities that you see in others rather than differences.
And of course, plenty of support here. This is a fantastic site.
