I had many evenings like that, especially the posting videos to facebook stuff and waking the next morning frozen with embarrassment. Why were the videos so embarrassing? I don't even know. I guess I just worried that people knew I was drunk.
I am glad to report that all of that crap stops when we stop drinking. It feels good to have control over what we do and say in person and online. The online thing was particularly traumatic for me as I could be in a blackout and post stuff that I couldn't delete til I woke up the next day at noon.
I couldn't live my life anymore with so much humiliation and you don't have to either. Welcome.
