My text in my TextMesh changes all TextMesh objects

I'm creating 3d TextMesh and when I change the text it changes the text for all of the meshes. I'm at a loss because I'm not even using public variables, let alone static.

Here's my script:

 public class TextObject : MonoBehaviour {
 
     private string text = "Hello World";
     private int tapCount = 0;
     private float tapWindow = 0;
     private TouchScreenKeyboard keyboard;
 
      
 
     // Use this for initialization
     void Start () {
 
         keyboard = TouchScreenKeyboard.Open (text, TouchScreenKeyboardType.ASCIICapable, false, false, false, false, text);
 
 
     
     }
     
     // Update is called once per frame
     void Update () {
 
 
 
 
         if(tapWindow > 0f)
         {
             tapWindow -= Time.deltaTime;
             if(tapCount >= 2)
                 DoubleTapped ();
         }
 
 //        if(keyboard.active)
 //            text = keyboard.text;
         if(keyboard.done)
         {
             
 
             text =keyboard.text;
             GetComponent<TextMesh>().text = text;
             if(text == "")
             {
                 Destroy(gameObject);
             }
         }
         
     }
     
     public void SwitchMode()
     {
         tapCount++;
         tapWindow +=1f;
 
     }
 
 
 
     
     public void DoubleTapped()
     {
 
         keyboard = TouchScreenKeyboard.Open (text, TouchScreenKeyboardType.ASCIICapable, false, false, false, false, text);
 
     }
 
 
 }

I removed some parts of the script because they're easily not related (Destroy, for instance). However, this is probably 95% of the script. What am I missing?
