If you're truly having suicidal thoughts please go to the ER right away. If not for yourself, for the babies. You're not only a danger to yourself, you're a danger to them as well.
If you're not truly having suicidal thoughts, it's not a very nice way to be dramatic.
I've had problems with suicidal thoughts at various times in my life, it's better to get help. A good doctor can find you some immediate relief with the right medication.
