I think I get the drift of what you're saying, Justfor1. Living my life day-to-day as a sober person, I sometimes stop and ask myself "So, this is how regular folk live their lives?" And sometimes I have an argument with myself, like when I lament the fact that I can't have a drink like a "normal" person, and then remind myself that "normal" people also don't start drinking at 1pm until they black out.
While drinking I always felt like an adult imposter, almost like I never really grew up in my own mind (despite the fact that I'm 30 years old). Being an "adult" was like playing a part, one which took a lot of energy. Now when I'm sober, I'm not nearly as concerned. I am much more capable of dealing with my adult responsibilities, and feel far less conflicted about them.
Sorry for the tangent, but your post hit a nerve today.
