advice without judging.

I am 14 weeks now pregnant. I jave 2 other children ages 12 and 7. my soon to be ex husband packed his stuff up and left us 2 weeks ago. Cuz he was cheating with a 19 year old. i am at the point now where i wake up every hour or so with my heart pounding and crying. I dont even enjoy being pregnant. Im 3000 miles from home and cant afford to go back. and i am barley making it by with my two that i have. Its.too late to terminate and he wont do adoption. so i feel.bad for saying this but im stuck. and alone and need a friend to talk too.
