is there a parallel experience like recovery for those who are not addicts but who also are going through stuff because their loved one is an addict or trying to recover from active using?
Absolutely! I've heard it said that, for every addict/alcoholic, there are at least five other people affected by their disease...family, friends, co-workers, etc.
In addition to Al-Anon, there are Nar-Anon meetings for family/friends of the addict. In the meantime, you will get plenty of support here.
