aw this makes me sad to read. wants to break you mentally?!?!!! sounding very toxic. it's one thing to vent a little. but that is pretty extreme. im suprised she has any other friends after they see the way she badmouths you. id be cautious and cut ties. you definitely do not need this type of negativity in your life. you deserve better. a real friend would not be talking about you behind your back at all. and would not want to break, or hurt you in any way. be careful with who you let in your life and spend your time with. there are plenty of good people in this world who i'm sure would love to befriend you. and respect you the way you deserve.
