Has anyone else experienced postpartum with their first and nervous about having it again with your second baby?

I had extremely bad pp ocd with my first, I am so scared I will go back to that dark place again with a second child. I want nothing more than to have another baby and give my daughter a sibling but I’m also very scared. Is anyone else dealing with this?

Also, I am terrified of having severe morning sickness like I did with my first. Did anyone have morning sickness with their first and not their second?

And I’m talking throwing up multiple times a day sickness 😅
