Time bomb

I... I don't know what's going to happen to me. I had an incident at school where I tried to off myself. I'm scared, I'm confused, I don't know what's going to happen to me, my future is covered in dark clouds. I got my family to take me in and get me admitted to the psych ward to try and get me help, but they discharged me saying that I wasn't at a high risk. And the voices in my head aren't exactly helping either. I have coping mechanisms, but I'm scared that I will turn to worse coping mechanisms. I'm a walking ticking time bomb waiting to explode, and I don't know what's going to set me off.
