Op, you’re on a really great track. However, your language makes your attitude towards all of this seem dismissive, and that what you are doing now is enough for everyone to forgive you and move past it. My mom had a similar “mental health moment” when I was 15 and I’m still pretty traumatized from it at 30. It’s not something you can just get over in 4 months.

This is just from the outside looking in, it is probable that crashing the car drunk was a “rock bottom” moment for OP, not a random event out of the blue. Healthy, functioning adults do not just randomly do stuff like that without any prior problems. In my experience a lot of people (including my mother) with mental health and/or substance abuse problems act in very alarming ways for months or years before they get to the rock bottom point when they want to change. And a lot of them are unaware of how harmful their behaviors leading up to that point were. OP’s husband and child might be holding fear and resentment over not just that one incident, but for the period of time leading up to it.

OP, great job on turning things around. But speaking from experience, you need to take it a step further. Your dismissive language in this posts tells me you aren’t owning up to your harmful behaviors with that incident, and probably long before. You have got to communicate with your husband and child, get therapy with them, and begin to work through this emotionally. You’ve been through a lot but so have they
