Revenge and deep desire for Justice is one of the symptoms of PTSD when it comes to experiencing a trauma from someone who abused are severely impacted ones sense of safety.

I have just read an article where it is now thought that "bipolar" can actually be something developed in an individual who suffered abuse/trauma as a child.

I am sorry you have these very strong emotions coming forward as you finally sort through your past. It's bound to present with strong anger and desire for justice and it's going to take you time to slowly gain more control over these very strong emotions.
Patience is of the utmost right now as you SLOWLY work on processing these very strong emotional challenges. You may need to be someplace "safe" while you work through this challenge. You are not going crazy, it's a lot of work to get to a point where you can find your way past the surge of anger and desire for revenge yet at the same time being very aware of how frightened and overpowered and helpless you were as a child.
