I know you are distressed but please do not give up hope. You are motivated to get help and that is very encouraging. The problem you are having is that you are not sure where to go for help or how to get it. The other issue is related to the fact that your family essentially does not believe in therapy and your husband mentally abuses you.
You recently visited a psychiatrist who was able to identify your diagnoses. My suggestion is that you speak to this psychiatrist about how to access therapy. The psychiatrist may be able to refer you to a therapist. I understand that your family may have a problem with this. If that is the case then you may have to hide the fact that you are in treatment. In some cultures, therapy is discouraged. I am not an advocate of lying but I understand that not everyone has an open mind or a healthy attitude toward therapy. There are certain times when lying is necessary and this may be one of those times.
I strongly believe therapy would benefit you. It could be empowering. A therapist may also help you through a divorce, should you decide to end your abusive marriage. Again, this would be going against what your family believes; however, it is important that you do what is in your best interest. Despite being abused, they want you to stay married simply because of cultural reasons. That is unacceptable. Divorce may or may not be right for you, but whether you pursue a divorce should be based on what is right for you, not on what your family and culture dictates you do.
If you cannot ask your psychiatrist for a referral, try searching this therapist directory. Contact at least 5 to 10 therapists and discuss your situation with them. You may want to look for therapists who are familiar with your culture. I am also concerned about the fact that you mentioned you would rather die than continue to live in your current living situation. If you are feeling suicidal please consider going to the emergency room. You could also contact the National Suicide Prevention Lifeline at 1-800-273-8255 and speak to a counselor.
The last comment I want to make this: I know you are going through a very difficult time. You are feeling hopeless but please do not give up. You were able to see a psychiatrist. The next step is to contact a therapist or other mental health professional who can assist you. You can be helped. Please do not give up trying.
