I feel stuck & depressed

I have a 4 year old, and am currently pregnant. I’ve just been feeling so negative lately. I’ve done so many applications to get a job but no one calls back. My husband works but he does landscape so some days he just doesn’t get to work. What am I going to do after the baby? I want to work… I want my own money. But at that point my toddler will be in pre-k and we’ll have to pay for daycare. There’s literally no point in putting the baby in daycare when my whole check is going to it and not leaving anything left over. I feel so stressed about it.
