I need a pick-me-up.. mom guilt..

I have a 16&1/2month old and I’m due to have our second in just under 6 weeks or less.. I’ve never been away from my soon over night, I’ve gone out for sure but I’ve always put him to bed and always woke up with him in the morning.. so labour will be 24-48 hours away from him! I can’t help but think he’ll be upset with me, he won’t sleep I feel very out of control with this and I’m probably over reacting, he will probably be less upset versus me....

how do I help this? He’s staying with my mom in my house btw. and due to the virus he’s unable to come to the hospital... UGH! I get so sad thinking about this... any one else experience?
