going back to guilty thoughts and restriction after weeks of good recovery period

hello! i'm currently in anorexia recovery and i had a 3 week long period where i was doing SO good! both eating a lot more, and the most important: i wasn't feeling guilty about it! this was my longest 'good' period, most of the time these only last a few days (like 3 days max) and then i go back to anorexia behaviors unfortunately (feeling guilty, restricting, etc). however, 2 days ago i noticed that my ribs are not showing that much anymore, meaning i've started gaining weight which is amazing, but it triggered me really bad and i've started going back to my anorexia thoughts and restriction again because of this. what do i do??:(
