PCOS & infertility - working toward motherhood

i was diagnosed with PCOS when I was 14 and have had constant weight struggles. I'm now in my thirties and desperately trying for a baby, but doctors won't help me until I lose more weight. I have 25 K's to go, but am struggling daily with diet, exercise and other health difficulties. I'm always embarrassed and other than my mum, partner and mother in law I've kept my struggles to myself. I'm feeling alone and quite disheartened every time I step on the scales. I'm looking for other woman who are facing the same or similar struggles so we can all work toward becoming mums together
