I think that is a huge step! I won't do it as I've got many extended friends that don't know and I've got 7 years in recovery. I'm also job hunting (working a temporary job) and as far as I know (have heard from people who hire), they can look at your FB page and do it often. That's just me.
My cousin, however, is in recovery and often posts really cool stuff about recovery - most of it relates to life in general, such as moving forward from the past and doing our best every day. I LOVE how he posts uplifting stuff that is from a recovery site but applies to everyone.
Hugs and prayers,
Amy
