Accept my reality

I have been trying to have a second child for 5 years, I get pregnant but I’ve had 7 miscarriages. Doctors cannot explain why and do not know which medical treatment to try anymore.  I am not ready now to make a cross on a second child but I know that chances to succeed are minimal or even impossible.  I process sadness and live with it.  Could you please help me to accept my reality and accept that I cannot fulfill this dream?  Thank you.
