felling sad and done in ttc#1 for 3 years now😔

Been ttc#1 for 3 years now! never ever been pregnant and never used contraception, don't ovulate at all and have no periods except if I take provera! Haven't have a "true period" in 10 years, I just don't know what to do😔 I have severe PCOS and nothing to help it with! I have tried everything and I can't get professional help they just don't care. I am booking a private antral follical count to see if I have any eggs at all as i have never ovulated at all,I am losing the will to live with this and can't take anymore I just want to be a mum so bad and I fear it will never ever happen😔😞
