Hello
You are definitely not alone in this. I also just joined today and this is my first day of sobriety. I know the feeling all too well of blacking out and not remembering what you've done the night before. And driving when you shouldn't after you've been drinking.
I too feel like I'm falling apart, but I think that since we've all found this community, we can rebuild our lives with a lot of understanding and support from others that are in and have been in our place.
