Overwhelmed and Underprepared

I currently have a 1 y/o and was engaged to her dad. A month ago, I found out that he’s been cheating on me for pretty much our entire relationship and we broke up and he moved out. Now I’m here alone, fresh out of college, no job and pregnant again! I’m excited about my Cam (the seed) but I am so beyond scared. I was just starting to piece ends together for the one that’s here. 😩 I’ve had miscarriages before so I’m trying not to panic but I am struggling!
