You already answered the question, if it's not going to end well then protect your Sobriety at all costs, alcohol is not the centre of the social universe, there are many people who don't drink or if they do it's secondary to the activity they are focusing on.
With new interests, will come new people, friendships based not on what's in your glass but on other common interests.
As for being a musician, it can be done, some of my inspirations prior to getting Sober were those in the spotlight and in that culture who now play a gig, go to bed with a cup of tea and nothing more!!
You can do this!!
