Another month of this

So i was 2 weeks late last month and now i have had my period since Nov 27 and still going. I have PCOS and honestly even my doctor feels like giving up. I feel like i wont ever get my miracle baby. Im so over this now and im emotionally exhausted. 2 of my friends had babies back to back and another 1 due next month. I want to be happy for them but im just depressed. I dont even care anymore i just cant stop crying😢😢😢
