I have heard that both post-partum and OCD can cause these thoughts. Can your family find you another doctor who might accept you?? Can you go to the hospital Emergency Department?? Your children will not be taken away from you for a mental disorder. Trust me on that one. What you have is treatable. Remind yourself it is not going to last forever. Try to keep distracted and focused on other thoughts until you get help. Keep posting here if you have to. Thoughts cannot hurt you or your kids. They are just ideas swimming in your head. It must be such a nightmare for you. Please turn to us whenever you need to. Keep us posted.
