I’m sorry. I can’t give you a definitive answer on the basis of this information alone. Either is possible, including that you have both.
Of more importance to me than the label is that you are so disconnected from people. People are social animals. We are wired to need and want to be with others for our emotional and physical health.
Disconnection can be the consequence of biology, trauma, learning or a combination. Whatever the cause, continuing as you have been will send you down a path of a lifetime of loneliness and probably anger (that you may justify as indication of your superiority). For that reason, I hope you are getting therapy.
You are only 17. However content you may feel with yourself, you also acknowledge that your feelings and behaviors are unusual; perhaps abnormal. There is great advantage in pursuing therapy now. Your brain is still developing. Your attitudes towards others are not locked in. You can set yourself down a different path.
Your letter shows you to be intelligent and insightful. These are strong, positive assets for therapy. If you commit to taking it seriously, you will do well with it.
I wish you well.
