I don't know what to do now. She cant do this to herself

Im freaking out right now, my best friend just texted my saying shes going to kill herself. Im trying to convince not to , but with what shes going through all I can tell her is No. without her Im all alone. I dont know what to do, Im going over to stop her, that and call for help. I dont want her to go, I dont want to be alone again. wish me luck, inside she knows im there but cant figure it out now.
