It's rather telling that you group substance abuse together with rather common and generally benign human conditions such as anxiety and neuroticism, and I find that your rather heavy-handed generalizations of people's capacity to help others based on their conditions and indeed their trauma dilutes your point.

It's as if you wish us to say, "I've figured everything out, let me show you the way." I don't find that particularly reassuring, and it's not exactly the kind of humility that I think you want to convey.

If your bar to helping others is ending all suffering within yourself, then I'm afraid we're all going to be living a very lonely existence if we followed your lead.

Now, I think your larger point is that folks in crisis should tend to that crisis, which I think anyone who has taken a plane ride would understand. Apply the mask on yourself first. But to extend that analogy, you can have a broken hand, or even a broken heart and still be able to help your neighbor.
