Hi, when I was feeling suicidal, calling crisis helpline helped me. I live in UK, so I was calling Samaritans. I see you are based in States, I found something like this:

Give them a call, talking may alleviate some pain, to at least bearable level.
Also, I heard you can go to hospital to accident and emergency and tell them you feel suicidal.
