My friend's pregnant and she's trying to kill her own baby...what should I do?

My friend is 15 and I'm 15 too.Her boyfriend is 16.She told me last week that she was pregnant and she's sure that the baby is his because she hasn't been with anyone else. She made me promise not to tell her parents or my parents and she hasn't told her boyfriend yet either.She wants to get an abortion but doesn't have the money and doesn't want to ask her boyfriend for it. Ever since she's been doing things to try and kill the baby herself. She's been eating all kinds of spicy food and drinking hot sauce straight from the bottle and this morning she was drinking vodka(she doesn't usually drink) just because she's sure these kinds of things will kill the baby.She even jumped off from the top of the staircase this morning at the park and made sure to land right on her stomach hoping that the baby would die.Is this wrong?What should I do?
