Welcome!
We have similar stories and we're similar in age, so I understand how you're feeling. It's tough to be 20-something and abstain from alcohol. Sadly, we've been taught to use alcohol for celebrations and entertainment, especially in younger ages. But, I can say this: if you are always drinking with your friends, you may find that when you're sober you may not actually like them as much (or the drunk version of them), which will make breaking some friendships off easier. ...Because you may need to cut some people out of your life for your sobriety.
I wish you well!
