As upsetting as it was that your friend went to the principal, it was a rather direct statement of intent. Now sure, you may not have meant this at all, you may have said it off the cuff, but consider, from your friends perspective, the state that you may have been in when you said this. You would have been a mess. And no doubt this scared your friends, as it was somewhat of a threat, in your friends eyes, even though you had no intent to carry through with it. A threat does not always need to show intent, when it's on this level I'm afraid, because that's a fairly serious statement.

The sad part is, even though you didn't have intent to go through with it, your principal has a duty of care to all students in his school. And if the roles were reversed and someone had threatened to physically harm you, you'd expect some sort of intervention.

Your friend, whether or not she asked you to text her or not, or to stop texting her, would have been upset by what you said, which is a reasonable response. If I found out a friend of mine was threatening to bash me, I'd be hurt.

You have a lot of emotions going on right now. Yelling on the forums by typing in caps, might just be the similar frame of mind that you were in when you were upset by your friends actions and people don't always know how to respond to this type of response.

I think what you're possibly reliving is the consequences of your actions. And yes, unfortunately in life, everything we do does have a consequence, sometimes good, sometimes bad.
