Creating offset for Physics2D.OverlapCircleAll

Hello everyone ,
I am trying to create an enemy that heals nearby allies when dying.
To achieve this i am trying to get collisions via Physics2D.OverlapCircleAll
I don't want to healer enemy heal itself , i only want to heal nearby allies.
So i created offset value for this. But it is not working.
Healer enemy keeps healing itself , how can i make ignore itself ?

Code (CSharp):

1.  
2. using UnityEngine;
3.  
4. /// <summary>
5. /// Clery is an enemy type that heals nearby allies while dying.
6. /// </summary>
7. class CleryController : BaseEnemy , IDeathrattle
8. {
9.     [ Header( "Clery Properties" ) ]
10.     public int        healRate   = 0;
11.     public float      healRadius = 0.0f;
12.     public LayerMask  enemyLayer = 0;
13.     public bool       isHealed   = false;
14.  
15.     /// <summary>

21.         {
22.             transform.position = Vector2.MoveTowards( ( new Vector2( transform.position.x , transform.position.y ) ) , ( playerInstance.transform.position ) , ( Time.deltaTime * movementSpeed ) );
23.         }
24.     }

30.     {
31.         const float offset = 1.0f;
32.         Vector2 healPos    = new Vector2( ( transform.position.x + offset ) , ( transform.position.y + offset ) );
33.         Collider2D[] colls = Physics2D.OverlapCircleAll( healPos , healRadius , enemyLayer );
34.  
35.         // If there is nearby ally.
36.         if( colls.Length > 0 )
37.         {
38.             Heal( colls );
39.         }
40.         else
41.         {
42.             Debug.Log( "Found no allies to heal !" );
43.         }

50.     private void Heal( Collider2D[] allies )
51.     {
52.         if( !isHealed )
53.         {
54.             BaseEntity tmp = null;
55.             int i;
56.             for( i = 0 ; i < allies.Length ; i++ )
57.             {
58.                 tmp      = allies[ i ].GetComponent< BaseEntity >();
59.                 if( tmp != null )
60.                 {
61.                     tmp.AddHealth( healRate );
62.                     EffectManager.efM.CreateHealEffect( allies[ i ].transform.position );
63.                 }
64.             }
65.            
66.             isHealed = true;
67.         }
68.     }

72.     /// </summary>
73.     public void Deathrattle()
74.     {
75.         // Heal nearby allies here !
76.         ScanAllies();
77.     }
78. }

Thanks for any help.
