Ttc#1 feeling bitter and lost

Me and my partner have been trying for 5+ years now and haven't had so much as a missed period. I'm currently waiting for blood results but all my scans and my partners s/count are fine apparently. I've endured numerous mental break down and depressive episodes . Every time a friend or relative or colleague announce a pregnancy I feel bitter and resent them. I've never been a jelous person but the last few years I have found myself very envious of anyone with a bump newborn toddler or child. I love my partner and I desperately want to give him the baby we both deeply want. We work so hard for everything we have but it feels like no matter how hard we work we will never have a family to call our own.

Any advice would be greatly appreciated please and thankyou xxxxxxxx
