Hi and welcome meuba13
I think rage is a pretty common emotion to all of us sobering up - mostly rage at ourselves, but sometimes at others and the world too.
For some of us, it's kinda the go to emotion for frustration and fear, I think.
In my case it kinda dissipated when I realised what a great second chance getting sober was - but it took a couple of months.
Like others have suggested if it's not getting better for you, maybe some counselling might help?
