I can sympathize with your situation Flowing. In the early days of my sobriety I can remember going to AA meetings and seeing all the smiling faces, thinking they were all a bunch of con artists. How could they possibly be happy not drinking?
For me life is a constant high. Of course life throws challenges at me (I found out recently I'm being laid off) but I never expected life to stop throwing me curveballs after I got sober.
The reason life is a constant high is because I've learned to truly love myself and take care of myself. In active addiction I would be the life of the party and yet still feel lonely in a room full of people. In sobriety I can be quarantined from society for months and still be happy everyday.
This didn't happen overnight obviously, it took many months of discipling myself, unlearning bad habits, and embracing better habits.
I'll repeat myself again and I say this without a trace of irony: life is a constant high for me.
