Alone and pregnant

I am alone and pregnant. Not by choice but he can't be with us right now and instead I am seeing all of these happy couples talking about pregnancy and engagements. That is legit all I hear about everywhere. And instead of any of that I am alone. I sleep alone every single night I have to go to my doctors appointments alone deal with all of the stress and I don't even know if he will be back when our son is born 😭 it is the worst feeling in the world knowing that everyone is loving the life that you could be but instead duty calls makes me so sick to my stomach right now 😩 he will miss out on most of my pregnancy and most likely the first few months of his little guy growing up. How can I be strong right now? I just want to scream. 😭😭
