Question: How to Keep TTC When You're Losing Hope

i thought we'd be pregnant sooner than this, it's been 8 months and two of my good friends are pregnant AND my younger sister just announced at Easter she's pregnant with her first. i'm happy for all of them, but can't help feeling down about this and like everybody's expecting me to announce soon, so it's making it harder especially at social occasions. DH is still upbeat, so that is good, but I'm spending too much time worrying. it is making it harder to ttc because i'm afraid of another BFN test. Anyone else feel same way?
