Im broken-hearted

I was 37weeks pregnant when my son came unexpectedly, via emergency

(his now 18months) C-section and was told after having him that there was to be no more babys as the lining was paper thin and i was on the verge of a rupture, im so heartbroken and its weighing me down and I dont no what to do? I know its not possible but how can I get passed this feeling?
