I do commend you.
When you say you're sober, is it drugs or alcohol you quit? My step-dad was an alcoholic for decades, my mom, sis, and I went through so much because of him. There was one time he tried grabbing the wheel while my mom was driving, her pulling the car over followed by punching her in the nose and pushing her out and taking off in the car. I remember back when I was in 8th grade he dragged out all of me and my sis' furniture and lit it on fire to get at my mom. He used to beat my sis whenever she ran his mouth to him, hell when I was a kid he caused my gramps to have to get stitches on his face. I used to avoid doing anything that might upset him out of fear, but even then that didn't stop him from taking out his anger on me from time to time. The dude following getting arrested after the one incident i mentioned with my mom, him facing prison time (didn't happen though since my mom didn't press it), he started going to AA , this being in 09 I think. But even then it wasn't until 2011 that he was finally completely sober, him sneaking beers for those 2-3 years, being a rollercoaster of mood swings. My life around him was a fucking nightmare, really it wasn't until 2017 that I'd say he finally calmed down and is alright to be around and is a different guy, him going to AA meetings once or twice every week, him getting really big into church.
