I am incredibly fortunate to still have loving friends and family who do support me.
Yes, you absolutely are. And I don't mean to be heartless, but I don't think you'll ever understand what that support has cost them, may still be costing them, and may never stop costing them, even if you maintain your sobriety. You'll get a taste of that here when you read our posts. If reading the devastation 'our' alcoholics have caused us helps strengthen your resolve, well, to paraphrase "You're welcome in our kitchen if you can stand the heat". But be aware that we will pull no punches with you (if need be).
So here's a bit of heat from my personal kitchen You're welcome to take it or leave it.
I have nothing but shame and remorse for how my actions have affected people.
My friend, I believe you. But that's not enough. Have you 'made amends'? I've taken the following from AA:
"In AA's Step 8, you're tasked with making a list of everyone you've hurt in any form and become willing to make things right. In Step 9, you take action—making direct amends wherever possible, unless doing so would cause more hurt and harm to the person you're making amends to. An apology is a statement. An amend is a change. When you make amends, you're not just expressing regret; you're aligning your behavior with your values. That might mean returning something you took, showing up consistently for someone you let down or choosing honesty where there was once deception."
Making amends is 'giving back tenfold to those you took from'. It can also mean a person telling you that they accept your amends but no longer want you in their lives. When that happens, you must walk away quietly. My DH has not yet learned to do that when it comes to our sons, who want nothing to do with him. DH is still at the stage of "But I've said I'm sorry!".
You will be in my prayers.
