Soldier- It does feel good to liberate yourself of what you have pent-up inside to your mom! you never know how she will react until it happens..but it seems from what you described as past behavior from her...she will still accept you and not "shun" you.
It always seems like a "hard core" dub's first suggestion is to tell the elders everything, she is programmed to think you have to spill your guts all the time...it takes getting a step back from the organization to realize that your life is your own, and "your heart" or I should say "your relationship with God" is no one else's business!
Good luck, keep us posted!
