GUI DrawTexture is sliding across the screen?

Hi,

I am trying to implement a sort of sanity meter into my horror based platform game and I want. I have the code working and it does what it is supposed to, however, I am now having trouble making it so that it's a textured box I guess. I am new and just learning t$$anonymous$$ngs and I have gotten pretty good at solving my own problems already, but I don't really understand t$$anonymous$$s problem or much about GUI for that matter.

 using UnityEngine; 
 using System.Collections;
 
 public class Sanity : MonoBehaviour {
     
     public float maxSanity = 100.0f;
     public float curSanity = 100.0f;
     public float sanityDrainSpeed = 100.0f; //# of milliseconds for 1 Health to drop.
     public string sanity = "Sanity";
 
     public Texture2D sanityImage;
 
     void Start () {
 
     }
 
     void Update () {
 
         curSanity = Mathf.Clamp(curSanity - (Time.deltaTime * (1000 / sanityDrainSpeed)),0.0f, maxSanity);
 
     }
     
     void OnGUI() {
 
         GUI.DrawTexture (new Rect (10,24, Screen.width / 3 / (maxSanity / curSanity), 200),sanityImage);
 
         Debug.Log (curSanity);
 
 
         //GUI.DrawTexture(new Rect(350, 10, Screen.width / 2 /(maxSanity / curSanity), 25), sanity + curSanity + "/"  + maxSanity);
 
     }
 }

So the problem is that if I use GUI.Label... it doesn't start to show decreased sanity until there isn't much left and then it just sort of gets smaller and smaller both vertically and horizontally w$$anonymous$$ch isn't ideal obviously.

Box is not ideal because it is just a plain old boring box.

Now, when I use DrawTexture, it does work except that as the sanity drops, the texture shrinks BUT it also slowly slides along the X axis.

I have no idea how to fix t$$anonymous$$s. Please, please help.
