Is it normal to crave for legal revenge? Can you help me in any way?

I mean in no way to minimize anything that's happened to you. However having a vengeful reaction is perfectly natural. After a while though you must begin to question how productive it is to your life to carry so much rage. Especially in the therapists case how much power you are giving them by allowing them to bring down your mood even years after you left. Forgiveness is not about condoning the terrible things people do to you. Its about doing yourself the favor of clearing your own mind of hate and people who harmed you, and allowing more mental capacity to then be used on yourseld. You deserve better than believing others wield such power over you. Now you are an adult and are in more control than you know. Go through with the legal proceedings if you wish it sounds like you could have a case. But this is not something that you should have any high expectations about it improving your life. Because you no longer see this person, you must realize that freedom and stop feeding your own anger
