There are many reasons to write apart from making a living from it. Therapy is just a word for what happens when you use text as a means to understand yourself. I use cognition (erkendelse), as it comes close to the action without really trying to give a practical reason. I feel that is at least also an undercurrent in your writings - not healing, but exploring.

I remember, but hasn't been able to find it that Norwegian/Danish author Aksel Sandemose in "A fugitive crosses his own path" writes about this strong urge after cognition. If you havenøt read it it might be interesting for you.
