I feel this a lot. I mean you're already doing it, but writing things out has really helped me. Externalizing it without just dumping it on other people. Something else that's really helped me is recovery type meetings, AA CODA, whatever you feel most aligned with. Can't speak for other groups, but my AA group is cool with any sort of Honestly, has helped me more emotionally than with addiction directly. Able to just pop off and rant for a bit and nobody minds because they're there to do the same thing. Having people there to validate your feelings really helps. People that you may not ever see outside that meeting! It's more limited so it doesn't have the same social issues that being dependent on someone emotionally.
