Thank goodness you are seeking help for yourself. You would be amazed to find out how much the proper diagnosis and treatment can do, to both understand what is going on, and how to fix it.
The only thing that doesn't look make it look sociopathic is your initiating some help for yourself. My sister is a true sociopath, at 53 years of age, and has never even acknowledged that she is sick. She is still deep in denial.
The best step in recovery is the first one, and no matter what your diagnosis is, there has never been so much help available.
Please get yourself in for a psychiatric evaluation, and remember that there is no shame in getting help, in fact it is the surest sign of strength.
Until you can make that happen, you might want to join an anger management group. This could be so helpful in learning ways to live with your anger, how to recognize the triggers that bring the rage on, etc.
Please keep in touch, I am interested in your story. Be well.
