Thank you for reaching out here. I admire your courage, sense of perspective, love of learning, and sensitivity for your daughters. The world is changing, and I can only imagine how difficult it is to feel used and oppressed in a marriage when you can imagine a better life. A quick search reveals that there may be some ways to use your master’s degree in the west, but more than that it seems like the disappointing and abusive marriage is the first thing to deal with.
My guess is that the panic attacks are related to your desire to leave and fear of your safety. What are your options? Who can you trust to help you with taking the next step? What is the safest way to proceed? As this article explains you are not alone, and there are risks. Yet is also seems from this article that this is a growing issue in your country.
My hope for you is to find the courage for you and your daughters. You may want to consult legal advice about your situation as this may provide you with a way of thinking about your options.
