Object flickers back and forth if it reaches mouseposition.

Hey so i made a script to move the object it is attached to to the position of my mouse. It works so far, but when it reaches my mouseposition, the object jumps back and forth and i have no clue why.

This is my code. Maybe someone can find my stupid mistake.

 private Vector2 mousePosition;
 private Rigidbody2D myBody;
 private Vector2 direction;
 public float speed;

 void Start ()
 {        
     myBody = GetComponent<Rigidbody2D>();        
 }
 
 void Update ()
 {
     movePlayer();
 }

 void movePlayer()
 {
     mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);

     direction = mousePosition - myBody.position;

     direction.Normalize();
     myBody.velocity = direction;
     
 }
