Detect Closest Game Object (with tag) To The Right Of Player Position (2D)

Hi,

So, following some documentation I was able to find out how to detect the position of the closest empty tagged "Teletarget". However, I am trying to figure out how to detect the position of the closest empty tagged "Teletarget" to the right of the player (2D game). Please help if you can! :)

Here's my current code (that only detects closest, not closest on the right, ahead of the player):

 public GameObject findClosestTeleportTarget()
 {
     gos = GameObject.FindGameObjectsWithTag("TeleTarget");
     GameObject closestTele = null;
     float distance = Mathf.Infinity;
     Vector3 position = transform.position;
     foreach (GameObject go in gos)
     {
         Vector3 diff = go.transform.position - position;
         float curDistance = diff.sqrMagnitude;
         if (curDistance < distance)
         {
             closestTele = go;
             distance = curDistance;
         }
     }
     telePosition = closestTele.transform.position;
     return closestTele;

     }
