I'm so angry right now!

I just completed my second IUI this morning and the doctor tells me that she has some testing from October she wants to tell me.  It's March my I remind you.  She tells me that my ovarian reserve that she tested in October was low and that my best chances are to do a donor egg!  That would have been nice information before I underwent a surgery and 2 IUIs.  What the hell!?  She also told me adoption was an option, as if I didn't know that!  I'm so depressed about all of it.  I just want to quit.  During this TWW, I need to seriously consider if I'm going to continue in fertility.  God is cruel.
