you just keep doing what you have been doing for over the last year, just take it a day at a time, a minute at a time if you have to and make that conscious choice not to hurt yourself. distraction is the key as i am sure you know. I havent self harmed in over two years yet it still pops into my head at least once a week to cut myself. And i am stable. It makes no sense to me why I would be thinking this still, but I do. I just dont cut. Dont keep any razors in the house so I am not tempted. So just continue using any skills you have been using in the past year. Get rid of any sharp implements you have so you can keep yourself safe. Tuesday will be her before you know it.
Hang in there.
