My Heart Doesnt know what to do

my heart doesnt know what to do it tells me one thing one day and then someone tells me something the next day and then my heart is stuck in a rut it doesnt know what to do it doesnt want to believe what the people r saying but then it does and then it thinks on its own and tells me it will happen and it is really and the feelings that it gives me r real and i do care about that person but i dont want to mess everything up so for now my heart doesnt know what to do so i dont know what to do.
