Let me just first say that it's a great sign that you're thinking about this. Many people with similar personalities would most likely not question themselves and see things in a one-sided manner, but you seem to want to change which is excellent. As for your condition itself, I don't think many of us here have the professional guidance to make a decision or to diagnose you because we don't know you personally. However, keeping a journal of things at all times might give you better insight into what goes on in your head. If you ever feel mad about someone or something, I'd suggest writing down your feelings immediately before acting upon them. This will give you clarity into your emotions and let you understand why you're doing what you're doing.
If you ever get the chance, you might want to see a psychiatrist (something I would hope you have considered). They will be able to properly diagnose and see where you should go in regards to your personality traits or emotions/desires that are unpleasant to you.
I think the most important thing is just to be aware of what you're doing at all times. Try not to let your mind drift. Try meditation and stick to a mantra. If your thoughts wander, come back to that simple saying that centers your being on something objective and not something clouded by your ego and emotions. Regardless of whether or not you have an antisocial personality, meditation will help you in many facets of your life and let you feel at peace with yourself!
Overall, although you may be unsatisfied with your current state of thoughts, I think it's great that you made an eHelp and desire to change! You're headed in the right direction and that's all you can ask of yourself! Keep it up!
