March 1st is National Self-Injury Awareness Day.
I feel the only responsible post to make is a resource post, so:
ASHIC: Self-Injury Awareness Day
American Self-Harm Information Clearinghouse
First Signs: Self-Injury Awareness Day (UK site)
Secret Shame (Self-Injury Information and Support)
Bodies Under Siege (forum)
How to go about finding and receiving treatment for depression
If you're thinking about suicide, read this first
Understanding Self-Harm (downloadable PDF booklet)
WebMD: Cutting & Self-Harm (Warning Signs & Treatment)
HelpGuide.org: Cutting & Self-Harm (Help, Support, & Treatment)
Cutting: Understand & Overcoming Self-Mutilation (book)
I've probably only scratched the surface with this post (or maybe not, because there is a distinct lack of resources available out there), and I've definitely only scratched the surface book-wise, so please share and add more.
