So depressed

I feel like I’m biting off more than I can chew. I’m not ready for this baby and feel guilty for been given this blessing and only wanting it taken away. My partner is unrealistic about the future, we have no money saved since it was a surprise baby, and once I have to stop working, we will fall behind on bills. I can’t stop thinking about how unprepared I am for this child, emotionally, physically and financially. I can’t express any concerns to my spouse without being completely blown off, I feel so unheard and unjustified in my feelings. I want to die some days. All I think about it the money we don’t have. Is this my future? Am I cut out for this? Can I even handle the hardship to come? I feel so selfish, but so strongly in my fears. I can’t sleep. They baby isn’t even here yet and I’m struggling to keep up with its demands of hunger. All. The. Time. I can’t stop eating and can’t afford to continue to. I feel so lost. Am I alone?
