So far you've made two steps forward, 1. your secret is out you posted on SR and I'm sure you feel some relief 2. You went to your first Al-Anon meeting which I remember how hard it was to walk into that room, but you did. Nothing needs to be decided right at this moment but starting to make just one plan is not overwhelming. Take some deep breaths, step outside for a few minutes, listen to the birds sing. This situation didn't happen in a day so it won't get fixed in a day, sorry I hate cliches too.
We're here for you anytime of the day or night. Praying for you.
