Nervous about Maternity leave !

I'm having anxiety about leaving my job as a waitress next week. Obviously zero paid leave. But on my feet all day is getting to me!! My hubby makes about $5k a month and I'm nervous without my extra income we will be so tight! Bills add up to $3200 a month. We already have a daughter who is in kindergarten and twins on the way in March! I'll be going back to work when I can, not full time though. Idk. Is anyone else in the same boat? I need some positivity! TY 💗
