You could absolutely learn to manage your behavior, but it's going to take a lot of effort and reflection, not only reflection on your own behavior, but also on others' behavior and how they handle situations. Learn by observing the best person in the room, both their strengths and weaknesses, their successes and mistakes. Adopt what works for you, and discard what doesn't. If you have no internal moral compass, you can still understand morality through logic the same way you can with emotions. Take up philosophy to help with this.

I would also suggest talking to a therapist, particularly one who's familiar with personality disorders. If you are ASPD, therapy can help you learn to function more easily in society. If you have PTSD or something similar and are repressing your emotions, then they're eventually going to come back and bite you in the ***, so it's best to start understanding yourself now while you're young enough to make substantial changes.
