No, you're overthinking it. I'm perfectly happy when I'm sober - I have a nice house, a great relationship, a happy family and tons of hobbies. I am in no way crippled by fear, social anxiety or trauma.
Drinking with my friends makes me happy in different ways. Alcohol doesn't lose its appeal just because I'm happy while I'm sober.
I agree an occasional drink with friends is fun, and different from abusing alcohol to escape negative emotions.
However, I think your description of external circumstances to argue that you are happy is concerning to me. People are good at ignoring negative things and deluding themselves, and happiness is mostly an internal thing and can't be measured by external success. I don't know you, but people with low self esteem in a narcissist/co-dependent marriage, with "tons of hobbies" to help them escape would still say exactly what you are saying.
