I can empathize with you.

When I am stressed or dealing with BPD I am very tempted to go back to restricting because it keeps my mind off of reality, it gives me a tangible although useless and unhealthy goal... logic keeps me from giving in most of the time but it can be very hard and I'll go through small spells where I'll exercise more than normally to burn off calories, be more aware of what I eat that borders dangerously on old restrictive habits.

I've only relapsed once from stress but that was terrible so I try not to anymore. But it's very difficult when anorexia and EDNOS is your 'escape route', the emergency chute out of reality, you know?
