Wow. This is horrible. So, from a psychological perspective you have it absolutely correct. You were manipulated, controlled, and brainwashed by this guy. Writing about it is a great first step to take. You have every right to be angry and disgusted and confused. Your parents are another issue that just compounds all the other issues you're suffering from. They should have been better. Its important that you go talk to a therapist. An MFT who you can just talk to about your experiences and say anything under the sun about, AND ALSO see clincal psychologist who can help you get into EBTs (Evidence Based Therapies), such as Cognitive Processing Therapy (CPT). CPT is used to treat PTSD. Mention that you might suffer from Complex PTSD. There are PTSD groups that might be worth looking into, which the clinician can enroll you in, just ask. The problem with therapy is that it takes a long time and many return visits over many months/years. The hardest part about therapy is not getting discouraged by it. It takes TIME. Getting discouraged will happen, but you just have to keep putting one foot in front of the other so to speak, and keep at it. Getting discouraged and wanting to quit is all part of the process!
