Struggling to cope

I am really struggling to cope with not getting pregnant, my husband and me having been ttc for 5 years and nothing! Loads of tests have been done and all have come back as fine! It's seems recently like everyone I know has just had a baby or getting pregnant! I'm so miserable about it and starting to even resent my husband, for not seeming a bothered as me. He already has a child who is ten. How do u all manage and cope with everything? X
