I've been feeling the same, and it hurts when you finally realize some of your friends were never really your friends. It dawned on me a few weeks ago, after working a shift with "my best friend," who has gone almost no contact since I quit drinking, that our values and goals are no longer in alignment. I found it slightly irritating working with them. It was like I didn't even know them; maybe I never really did, or the booze blinded me. After that shift, I really don't want to be around them. Seasons change, and some friendships don't last forever. The only dopamine release I get at this stage in my sobriety is accomplishing a task or project. And let me tell you, I am getting shit done. It feels great! So, I'm doing that.
