I have had this experience, long ago now. You will need to grieve in your own way. And somehow remember that the others, whatever they did to you, are somehow "dealing" with or "experiencing" their own troubles though it is awful hard to see what they might be.
Remember, we are here, we do care, and that means, us being real people in the world, there are others out there who do care/can understand. Take all the time you need, but do not berate yourself, or allow the acts of others to determine your path. You cannot give them that power, it is a life-sucking, demoralizing place to live.
Time, patience, break it down to steps towards your own light. (yeah, I know, easy to say, but, give yourself all the time you need, just don't let it damage you forever, although the experience will linger on, pop out at inopportune times, and change over time...)
