mother in law bipolar

What should I do my mother only threatened to crush my *** and she is a redneck say bipolar?
I did say something about her and her shouldnt've I listened on the phone … I am in fear for my life. the woman is just as afraid of it, so I'm on my own here. I'm talking seriously, ya'll can not see me again. What should I do?
grab a skillet and a metal spoon, beat in the face when she comes then will stitch head and run for an hour while she's recovering
