29weeks 40yrs old! can I do this really?

Liz
Hi I'm 29weeks with a little girl we have tentatively called Emily, she's got truncus arteriosus and a leaking heart valve so will need surgery as soon after birth as possible if they can do anything 😢 they don't really know until she's born. I'm so stressed having a section on 17th July she will be in hospital for at least a month! But I'm so worried about how my 10yr old will cope too! He's really sensitive and we are really close so I will probably miss him more than he misses me! 
I'm panicking as we have nothing ready for the baby and I just don't know how I'm going to cope or my son and husband. Feel sick to my stomach thinking about it!!! 
My last pregnancy was so easy no problems and he was perfectly healthy, it's going to be so hard. I don't know how women carry babies at 40 I'm permanently exhausted already! On antidepressants as struggling but I'm just so scared 😢 sorry pity party over x
