Two years sober and being a present dad again

I'm not going to go into all the details of what I was doing before but basically I wasn't here. Even when I was physically present I was checked out. Hit rock bottom about 2 years ago and decided to get help. Went through rehab, still do meetings, have a sponsor. My kids barely knew me when I started this. Now my 7yo runs to the door when I pick him up. My 10yo wants to hang out with me on weekends instead of being dragged along. I'm not gonna lie and say everything is fixed or perfect but I'm actually present for their lives now. That's the biggest change and I don't take it for granted.
