If you want to be understood as a jw, then your best chances are online, by either post or pm. Not many people in everyday life have an idea or want to know.
In time, your wish to be understood as a former jw will give way to being understood as everyday joe/joanne.Then the former won't matter as much as it does now.
As for some formal method of support aka the buddy system, I dunno. Roll the dice.
