C# 2d Instantiate GUIText and lock it to position on map, not to follow camera.

Hello. I am having a really hard time trying to work with GUIText instantiation. I want the instantiate to be placed correctly just like any other GameObject instantiation, but it works too mysteriously for me. I have atleast managed to make it spawned at the correct position initially, but it still happens to follow the camera when any other movement of the camera is made. So, I want t$$anonymous$$s to not happen. I want t$$anonymous$$s to have its own fixed position on the game map.

Relevant code:

  public GameObject textGUI;
 
         void OnTriggerStay2D(Collider2D col) {
         if(col.gameObject.tag == "Food") {
             //Add to current health
             curhp += 5;
             FoodPoint();
             audio.PlayOneShot(munchFood);
             Destroy (col.gameObject);
         }
     }
 
     void FoodPoint() {
         Vector3 pos = Camera.main.WorldToScreenPoint(transform.position);
 
         pos.x = pos.x /Screen.width;
         pos.y = pos.y /Screen.height;
 
         GUIText obj = GUIText.Instantiate(textGUI,pos, Quaternion.identity) as GUIText;

There is more stuff that is incorrect at the moment, like passing on new information to the textGui. It is none of my concern at t$$anonymous$$s moment. I just want to know how I can instantiate on the game map, not the camera. Thank you for any help.
