Anyone else doing this journey alone?

My husband left me on Monday... has no plans to come back. I’m 18 weeks pregnant .. obviously scared, I have two other kids to take care of, I work part time & I can’t even begin to believe this is really happening.... my mind is such a mess, I have cried every minute of every day. My eyes are so swollen and looks purple, but I have to go to work & pretend I am okay... he is coming tonight to pick up his and my step daughters stuff.. he has messaged me a few times just to remind me he isn’t coming home, that we can’t fix this and even told me he no longer wants this baby.... (all he ever wanted was a son)... we are having his son. We found out last week, he cried tears of joy... but today... I am broken, I am hurting, I am scared and I don’t know that I can do this on my own 😭😭😭

I’m not looking for sympathy, just hoping someone, somewhere can relate... tell me this gets easier. I have barely slept, I’m not hungry, I am seriously so broken. I laid down at 2 am .. woke at 3:07 in hysterics, face covered in tears, couldn’t catch my breath... hoping this was a terrible nightmare. But apparently; this is my life now 🤦🏼‍♀️😭😭
