It’s not just pregnancy. I’m sad

My husband told me tonight that I was already a bad mom. I’ve felt sad, lonely, inadequate, like my life didn’t have a purpose for the past few weeks. And it’s only getting worse. I’m angry. I’m hurt. I decided I didn’t care. I cleaned the cat litter out and now I’ve been crying for hours because I know I shouldn’t have. I feel so lost. I want to be happy about baby. We were ready, financially, mentally. But now that I’m pregnant, it’s hard and I’m tired and I’m not happy. Please tell me I’m not alone...
