I think it's because recovery is hard. It's easy to theorize about what techniques are available, what the steps to recovery are, come up with ideas. But putting them into action for yourself is very challenging. I constantly am working on convincing myself that I'm ok, even though I know I'm not, and when I have a good day I am further convinced that I just need to "get it together". I would never tell another person to do that, why do I do it to myself? It's my mind playing tricks on me I think.
