Keeping faith when TTC

How do you guys carry on.... i fee like less of a women and useless... i have a 1.5 year old and we have been trying since my baby was 9 months due to i was scared that my PCOS would flare up worse then before and completely prevent me from having any more... PCOS said bad that when the doctors found out i was pregnant with my first they didnt know how and told me over and over again he might not make it.... i have prayed and prayed for God to grant me another... cryed myself to sleep and still no luck.... 😞
