I'm sceard about a friend of mine

Im breaking down I'm sceard she's gonna do something I can't be there for her physically but I sent her long texts telling her that she's not alone that she can call or text me any time she needs someone I told her how Great of a human she is how kind hearted and pure she is that i,ll be there for her. but I can't calm down my mind. I'm sceard she'll do something bad.
