I hear you. You feel like a loser. You are lonely.
I'm painfully aware of what that feels like because after all these years I still feel that way at times...maybe not often, and not for long, but painfully and sometimes.
You were in rehab. Did you have a plan when you got out? Did you work the plan with all your heart? Are you reaching out to a community of people who have the same problem you have?
Speaking of having a good day...there is the old saying, "My best day drinking was worse than my worse day now."
It's probably not really true and may even be a little stupid to say such a thing, but there is something to the gist of it.
