Learn to ask for help. A lot. When you start getting well you can always return the favour.
Sounds obvious, but the reason I could never stop before is I never knew how to ask for help. I thought others "magically did it". Now I've got to day 83 by asking for help when I've wobbled (online, called friends, or face to face). People have always been there to catch me when I've asked, and the next day I've always been so grateful that I reached out.
