I vote for option 1: Seek help. You are a young man who has been deeply, deeply hurt. When people’s feelings are very hurt, one common response is to want revenge. But revenge never really helps. It only adds another layer of distress. I think you know that since you wrote to me instead of just going out and exacting revenge.
You have the additional challenge of Aspergers. Sometimes Aspies have a particularly difficult time letting go of an idea, even when it is a bad one.
Unfortunately, I’m not familiar with what services are available in Scotland. I urge you to talk to someone who does. You didn’t mention your mother. If she is in the picture and you trust her, that’s the place to start. Someone at school, a pastor, or your doctor are other resources.
I’d hate to see you do something at 14 that harms others and that would send you into the legal system. You have a long life ahead. Get the help you need so you can have a good one.
I wish you well.
