Pcos, feeling alone

I feel so alone right now, I haven’t stopped crying for 3 days. Me and my partner have tried for 2 years and still nothing, we’ve tried all sorts but when I try speak to someone they don’t understand how alone you feel, questioning why you and why your body is like this. Seeing baby and families everywhere. I just can’t cope with this, it’s so hard to think about a life without having a family and also the fact I feel like i’m holding my partner back is just horrible 😭
