Hello my friends, 

I'm not sure if any of you know about this app for your phone but I just found out today! It's called 'Calm Harm' and helps you manage or resist the urge to self harm. I don't cut as much anymore so self harm for me is any type of destructive behavior whenever i feel very emotional. 
I haven't used it yet, just browsed it, but it seems really promising and has good reviews. I never had DBT but it reminds me of it? I think it's based on it. 

Basically, it tell you emotions are waves that come and go and it gives you tasks to help surf the urge of SH. There are 5 categories: distract (helps with self control), comfort (caring for yourself rather than harming), express yourself (getting the feelings out in a different way), release (safe alternatives to SH) and breathe (breathing exercises). You can do the activities for blocks of 5 or 15 minutes. 

I think it's worth a try!
