Try to find something to distract yourself. Watch a show, listen to music, ANYTHING. And you CAN do it. Writing a post on here was the first step in reaching out and asking for help. Control is not lost, you are demonstrating it right now. You have demonstrated control by not hurting yourself for the last [insert] time. Each second or minute that passes without you doing anything to hurt yourself is an act of control.

Of course, if you truly feel like you can't fight these feelings, then please try and get yourself to a hospital or somewhere safe. No body can deal with such intense feelings without some sort of support... it doesn't make you weak. It shows your strength.
