Why do I do this to myself?!?

I am having a really hard time getting motivated at the moment. Up until Christmas I was focussed as I knew I could have 1 bad day on Christmas so that kept me on the straight and narrow but since then I've not been nearly as good as I was and I'm only 4lbs from losing my stone. Its my 3year anniversary in the 1st week of march so I'd love to reach my stone by then...

Anyone been in the same boat or hot any advice I'd greatly appreciate it! Really struggling
