What’s wrong with me

I’m 5 weeks pregnant and I’m just feeling really depressed and anxious, it doesn’t help that it’s dark and smoggy outside all day everyday, I’m just worried about how my husband and I are going to fit this new person in our lives, how we’re going to have to change our finances and live smaller, I’m obsessing over everything we don’t have when I was perfectly happy before. I haven’t slept well in a few nights I find myself awake halfway through the “I can’t do this” thought. I find myself mourning my old fun low responsibility life, my career ambitions, I fear that my entire identity is going to change.

We’re not in a dire position we have a great relationship, we have stable income and a nice home.

I don’t know what’s wrong with me, I was so excited to have this baby.

Did anyone else feel this way in the beginning? Is this a sign that I’m going to be a horrible mother?
