Here's a list of five things you can start practicing right now that will aid your recovery both in the moment and over time, quick and dirty:
Practice expressing your feelings.
Practice asking for help.
Practice saying no.
Practice calming breathing (inhale on two, exhale on four).
Practice eating *something* every three hours.
Also, notice when you are able to do any of the above, and how come. What was different this time that helped you practice one of these skills instead of or before engaging in behaviours?
