It may not feel like it, but you're doing a great job. As I said on another thread, reaching out is half the battle.
I'm in a similar situation w/my family gone this month. I've had thoughts of drinking because "no one will ever know." But then I remember I'm 2 months away from having 3 years of precious sobriety under my belt. This thread has been a great reminder that I'm not the same person I was 3 years ago. I rewrote my story - just like you. We don't drink anymore - it's just not who we are. I,for one, thank the universe for that.
Stick around & keep posting. It works when you work it.
