You can stay strong. Some of the things I do to try and help stop the urges are trying to sooth myself. Taking a hot shower or something relaxing if you can get your mind into it. Distractions help me too. I try to get myself wrapped up into something to occupy my mind. Sleeping also helps me.

If those don't work there are less harmful ways or alternatives to self harm. Holding ice cubes helps some people. It causes a lot of pain, but doesn't cause injury (unless you hold them too long, then there is frostbite). Eating really spicy food can illicit the same release of endorphins. Mexican or Thai food can be spicy. Another method people use is to draw on themselves. It may satsify the ritual of the act and help you express yourself without harming.

No one is perfect we falter sometimes but don't beat yourself up over it. The key is that you can try to sooth yourself and control your urges to self harm. Even if it is only for a day or even for an hour, that is progress. I find being around people I like help me from doing it. I stay connected and stimulated and don't obsess over it so much. I hope things get better for you. If you want someone to all to you can PM me.
