Emotional breakdown help

Really just drowning in my feelings right now and need to vent to somebody so hoping my fellows moms can “listen”. I’m pregnant with my 3rd baby. A baby I thought we wanted. All of our babies were planned and prayed for. But this time around just makes me feel 100 times more distant from my husband sexually making me feel like crappy wife. I’m so drained I feel like my other kiddos barely see a happy mom. (I work full time) and financially maybe wasn’t the smartest choice to have another baby. I never want to regret my babies but this one just feel so burdening and I hate feeling that way…😭 our other babies took a while to conceive and we thought this one would be the same. And we’d have time to prepare more mentally and physically but it happened first try and it just is hard.
