RaycastHit2D hits "itself"

I have gameobjects with circle colliders, and walls with box colliders. I make raycast to detect if there is something in front:

  RaycastHit2D hit = Physics2D.Raycast(transform.position, currentNode.position);

However when I write the name of gameobject which raycast is hit, it shows me that it hit itself.
Do I need to disable my Collider and then enable it after raycast? I know that there is masking, but I can’t use it, because other gameobjects will raycast too to detect this gameobject. Any Ideas?

you should put yourself on a layer ,make a new layer for example layer 8 and assign it to your object and then tell the raycast to do its job on all layers except your player layer, like below

 int layerMask = 1 << 8;
    // This would cast rays only against colliders in layer 8.
    // But instead we want to collide against everything except layer 8. The ~ operator does this, it inverts a bitmask.
    layerMask = ~layerMask;
    RaycastHit hit;
    // Does the ray intersect any objects excluding the player layer
    if (Physics.Raycast(transform.position, transform.TransformDirection (Vector3.forward), out hit, Mathf.Infinity, layerMask))

Try using a Trigger Collider.

My solution was to turn off the collider before the raycast and turn it on at the end:

for (int i = 0; i < sectorCount; i++) 
locations *.GetComponent<CircleCollider2D>().enabled = false;*

RaycastHit2D hit = Physics2D.Raycast (locations .transform.position, Vector2.up);
locations .GetComponent().enabled = true;
