I’m so depressed

I LOVE and adore my daughter. She’s all I’ve ever wanted and I’m not being ungrateful about all the things I have in life and I appreciate it all but why am I so unhappy? So stressed and bitter. I feel like after having a baby idk who I became and I’m always snappy. Not at her, I take good care of her and show her so much love and attention but with my husband. Idk who I am anymore. I feel like I’m failing at all aspects in life. I don’t cook anymore, house is a mess, I don’t bother washing up or dressing up how I use to, I haven’t been a good wife. I feel overwhelmed. I’ve tried explaining this to my husband before but he doesn’t help or support my emotional needs. And that shouldn’t be on him. Then I feel more like crap for feeling like this. It’s like every morning I wake up great happy and then as the day slowly goes by I turn into a grump and all mean.
