D&C at 11 weeks

I found out at my 11 week appointment that there was no heartbeat, after seeing a strong heartbeat many times. I had a D&C yesterday and am trying to be optimistic but does it ever get better? Will I ever stop crying? I’m crippled with fear that this will happen again or I’ll have trouble getting pregnant. How long did it take you to conceive after a miscarriage? Looking for some optimistic stories 😞.
