hi Sher8907,
look at the sticky threads a t the top of the page and they have lots of ideas of what to do instead - that may help
are you seeing a T? they can help too.
most of all - it doesnt stop the numbness - it just gives you another problem to deal with -
I am sorry you are feeling in such distres that you want to harm yourself - its probably because someone else has already harmed you? dont let the darkness win - hold out if you can - call a friend - post here - write down everyword in your head until it stops - please be kind to yourself and dont hurt yourself - please be safe P7

Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
