Well, it depends.... there is frequency and severity. For me, I was doing it extremely often-- my arms and legs were literally covered with cuts-- but none severe. They were mostly superficial injuries. It also depends what is going on along with your SI-- for me, I was having so many panic attacks per day, I could barely function. I was also very depressed. Many factors go in to whether or not one decides that a hospitalization would be beneficial. It's not just like-- oh, you cut 5x per day. Well, that's outta control, so you need to be in the hospital. It has a lot to do with what's going on along with that behavior, you know?
