how can i prevent relapse?

[mth]

Hi,
I've suffered anorexia as a senior in highschool but recovered once I went to nursing school (It's been almost two years and I just turned 20). I decided that I needed to focus intently on my studies and I was able to give up the bad habit. I'm worried now that I'll be graduating that I'll fall back into anorexia. It's always on my mind, but when focusing on school work, it's easy to resisit. What can I do to prevent relapse once I'm back at home and out of school?
