This is the beauty of the understanding of "you have to do it for yourself".
On the surface that post looks like the quitting is being done for the children. The sentence doesn't read "Having my adult daughters seeing me in detox made me realize that I had to quit for them." It ends with "pretty much did it for me". She knew that was it. She made the decision to quit for herself and due to that her adult children will never have to see her in detox again. That's what I mean by it has to be for you and your family reaps the benefits.
