Welcome to SR MissGinger, have you considered hanging out with sober people your age that have walked in your shoes and now know how to stay clean & sober?
I have been through Charlottesville quite a bit on my way to the in-laws who live west of there.There are a ton of college students in that area and I can assure you that there are a number of AA meetings either right on or right off of campus.
You are far from being younger than the youngest people in AA, we have quite a few in my area that go to Mary Washington along with a few HS students as well.
Do you think it would be easier getting and staying sober doing things with others your age who are sober?
If you do why not check out some AA meetings? What do you have to lose? A drinking problem. What do you have to gain? Possibly a new life with new sober friends!
Hang around here, ask questions, share struggles & victories.
