Unity C# Bomb Radius Issue

Hey all,

so I've been pulling my hair out for weeks now, and I've tried every tutorial out there and I can't seem to find anything on how to fix my issue.

Basically,I have a bomb that is instantiated at the players location on input, runs down a timer, and then if anything is inside it's Physics.OverlapSphere when the timer hits 0, deal damage.

The problem is, that it will always hit me, even though I tried getting it to only deal damage if the gameObjects tag == "enemy". What's worse is that even though I'm SURE I left the radius, it still thinks I'm in there.

 if(currentBombAmmo > 0)
         {
             if(Input.GetKeyDown (KeyCode.V))
             {
                 Instantiate(bomb, transform.position, transform.rotation);
                 Debug.Log ("Bomb has been planted!");
                 currentBombAmmo -= 1;
                 bombActive = true;
                 audio.PlayOneShot(bombDrop);
             }
         }

 if(bombActive == true)
         {
             bombTimer -= Time.deltaTime;
             Collider[] around = Physics.OverlapSphere(bomb.transform.position, bombRadius);

             if(bombTimer <= 0)
             {
                 foreach(Collider inExplosion in around)
                 {        
                     if(inExplosion.transform.tag == "enemy")
                     {
                         Debug.Log("bomb has hit some enemy");
                         gameObject.GetComponent<healthScript>().characterHealth -= 110;
                     }
                 }
                 audio.PlayOneShot(bombExplosion);
                 bombActive = false;
                 bombTimer = 5.0f;
             }        
         }

Also it seems to only work for the first bomb. If I drop the second bomb, the timer works fine and all, but it won't do anything else.
