Sorry to say I was involuntarily committed for SI. In the state I was living in at the time, there had to be a Dr., parent (even if you were 18) and someone else with clought in order to do it. I'd been going through an intense period of suicide attempts, but was also cutting. Those were put off as more attempts.

One night my friend drove me home and asked to come in the house with me. Inside, there were my parents, the family GP, a counsellor i had known and my friend. The told me I either had to committ myself or they would do it. I felt badly betrayed at the time and it took a long time to get over. I too wound up signing the papers. Since it was a late Friday night, there were no pyschologists available to evaluate patients and I didn't see one til that Monday. Even then, he just sat me down on a bench in the hallway and asked what was going on. I wanted out, so I told him what he wanted to hear and was released.

I can't say as I wish they had kept me because by then, I'd been through a bunch of psychiatrists that probably should have themselves been committed and wanted nothing to do with them. Had someone gotten to me as an early teen when the problems started, I probably would have been more receptive.
At anyrate, committing someone without thier consent doesn't seem like a very good enviornment. Its more likely to cause resentment and defensive behavior. Now I think you have to be in imminent danger of hurting yourself or someone else to be committed.
