You’ve got this. My eldest was 2.1/2, 2nd was 11 months when the 3rd bubba was born. I was petrified, same feelings of wanting to run away. However they are now 27, 25 and 24. I told myself to take it an hour at a time. Weirdest part is 11 years between no. 3 and no.4, then 5 years between no.4 and no.5. So 20 years between no. 1 and no.5. It’s been hectic and some days I’m tired but keep taking it an hour at a time. You’ve got this💪
