Personally, to an extent i have to agree that priority to wound recovery should be given to those with accidental damage.
Alot of selm harm is actually done to attract attention, No matter how much these said depressed people say they want to be alone etc, by self harming and then letting others find out, its a cry for attention, for help.
The people that really need the help are those that are past the calling for help stage. The people who do it for reasons other then for attention, and thats where the problem lies. Because they dont want attention.. they dont get it.
