Exactly...Toni, you are in the right place. We are your peeps for dealing with real life, not as we imagine it...sober.
I dont have kids either, but I have friends and family of all stripes, in and out of every kind of closet. I also know I thoroughly disappointed, betrayed, and embarrassed my parents, in ways large and small, in ways they are and are not aware of. Your son is trusting and trying you. You will both find your ways with trust and respect and love. If you hold onto those, even imperfectly, and stay sober....you are being who you and your family need you to be. And that is all we can do for anyone.
Edit: and by all means, seek additional appropriate support. More is more in this case! We all have more than one tribe, I am sure.
