In the past I have self-mutilated and recently there has been a lot of added stress to my life. I've heard about wearing a rubber band on your wrist as an alternative. I was just curious are there any downsides to this method, as an example I have been doing this for a week now and I have gotten a bruise on my hand, it probably isn't from me snapping the rubber band but I was just wondering if there is anything I should know about this method? Thanks
