I can’t protect my baby out here, please stay inside me

I see so many women in pregnancy groups and all over my facebooks just so deathly excited and eager to see and want their babies out but I’m sat here in bits knowing he’s got to come out and will be here by December. I’m not ready, financially, emotionally, physically and well I can’t protect him as well out here as I can when he’s inside me?

I feel so much stress, anxiety, pressure and depression even thinking about it that I’ve tried just spending hours keeping myself busy to the point of physical soreness so that I don’t think about it, someone please tell me I’m not alone with this?
