Boyfriend in jail and I’m pregnant

My boyfriend is in jail and im 16 weeks pregnant .. he might be doing some time 😔 no he didn’t kill anybody itwasn’t nothing that serious .. but everybody makes mistakes sometimes people make them bigger than others .. he’s the love of my life and I feel miserable I can’t stop crying ... everyone tells me to not stress the baby but sometimes it’s so bad that i forget that I’m pregnant I’ll cry and cry then I have to remember that I am and stress is not good on baby ... I started throwing up and not wanting to eat and I feel like I’m slipping in to depression I know I have to be strong for my child but the thought of his/her father is goin to miss their birth ?? Or even maybe their 1st birthday ... I feel so lonely I have no friends ... I asked my sister to come sleep at my house but she’s always busy 😭😭😭 I’m freaking out !! Can I get some advice
