Feel like jumping off a cliff......

My toddler is going though this whining for EVERYTHING phase right now and it’s sending me through the roof. Literally all I hear is crying all day everyday..she cries in the car. The WHOLE entire car ride. Cries everywhere we go. Cries at home for Amy and every little thing . I just don’t know how much more I can take anymore , I’m really going into depression at this point cause it’s like NOTHING can satisfy her at all. Like what am I doing wrong .
