How do I stop the urges?

Whatever works for you. Reading... color in a coloring book... drawing... writing poems. Something to distract your mind for about 15 minutes. Hopefully those urges will be gone by then. If not... move on to another activity. Or just find someone to talk to--if you don't feel like talking about your problems to your friends for whatever reason even just texting/calling a friend can take your mind off things

I feel that urges for anything are usually the outcome of some underlying emotional cause. It is best to find out what is causing the urges, and work on that with a professional, rather than trying to stop the urge itself.

Urges are tough, from personal experience, but can be overthrown! Here is a link to an awesome resource with many coping skills and distractions for self harm: sirius-project.org/2011/08/16/distractions-and-alternatives-to-self-harm/ . There are so many out there, my personal favorites are doing things that make me happy (such as watching netflix, going for a run, dancing, singing obnoxiously in my shower, eating chocolate), taking to someone (to a listener on 7 cups, to a therapist/ counselor, a friend or family member), and silly things such as writing out my feelings then throwing the paper out, freezing an orange, then placing it on your wrist when I have an urge (You can use all your 5 senses for this one!), snapping a rubber band and drawing on my arm.

Keep your hands busy. Find other things that soothe the feelings you get from self-harm. If it gives you a rush, try making a goal to ride every roller coaster out there. Things like that.

The best way to stop urges is to Divert your mind. It can be a small thing like taking a walk or planning something out with friends or even starting the hobby you never got a chance to do !

I think the best way to stop urges is to divert your attention by focusing on productive activities.

You replace those urges or negative habits with healthier positive ones. Once you feel an urge coming start doing that positive habit and distract yourself from the urge.

Always find something else to do. Pet a cat, watch a movie, make some art, make some music. Anything to distract yourself.

Help to identify the trigger for the urge and reinforce good behavior when the person can themselves identify and stop before engaging in the activity.
