I would say give it a while to rest and then try to reconcile. Not just with an apology but with concrete actions what you will do to prevent it in the future. I always advice people to set boundaries, your friend just did. It's going to suck going back. They don't owe you, but that doesn't mean they might be open for another chance.

I do feel for you, I am struggling with some mental stuff and hooch too. I always internalize and acting out is just not in my system. This is no brag, I just wouldn't want to imagine the pain losing your friends would be.

You said you are already in therapy, I hope this is a topic you can discuss. Because this hurts. I hope you can take a detour from alcohol, its clearly not bringing out your best side. It rarely does with anyone. Keep working on it and talking about it.
