Hello and welcome!
It is tricky to make new friends as an adult, specially in a new place. I commend you for moving and having a refreshing new start. I would suggest that you take your kid to the library, park maybe enroll them in a class. Volunteering is also a good way to meet new people.
You have great incentives to change, your child and your liver and as hard as it is, it's really simple. Don't pick up that first drink, or hit... This place is a great resource. Read around and post when you need to or want to. I have learned so much about recovery, self-help and alcohol that it has really empowered me to make the change.
Hope to see you around.
