How long til I feel like myself again?

My little one will be one month on Saturday. I am over the moon with love for her. But with my husbands busy work schedule and the lack of help I get from him, on top of trying to give equal attention to my 7 year old as I do to the baby and trying to keep my house clean and look after our dog which for some reason has been a ton of work lately I’ve been feeling stressed out and overwhelmed. I’ve been feeling extremely irritable.

I also haven’t felt like myself at all. I no longer find joy in listening to music or watching Netflix. I find myself just sitting there either staring at my phone or doing absolutely nothing. My husband says I’m weird since I just sit and do nothing but I honestly have zero motivation and I hate the criticism from him. And when he’s not home I just feel sad and lonely. I’ve also been feeling ugly with such a low self esteem lately, yet I don’t have the energy or motivation to do my hair or throw some makeup on, some lady at the coffee shop the other day even asked me if I had another baby in my belly as I still looked really big. I don’t think it’s PPD as I feel so close with my daughter and could snuggle with her all day. Anyone else feel this way? How long did it last? I feel most sad in the evenings, in the mornings I feel happy and energetic.
