Ttc, why am I so worried

Im ttc, and I think it’s really really stressing out. I have an 18 month old girl, who is wonderful, I have a great little house and a generally sweet husband.

So wtf. Why am I obsessing about not being good enough for a second child.

I don’t know if it’s Covid and isolation from lockdown, or having a really bad ectopic 10 months ago (doc didn’t see the baby in my Fallopian tube until the second trimester and after rupturing 3 times, I finally got checked out and lost my tube), or noticing things about my own mom more recently (she’s a really self oriented alcoholic), or none of the above... but whatever it is I’m really really anxious.

I’m worried that my body is flawed or my genetics are bad. I’m worried about losing the baby late term.

Anyone have any advice or in a sort of similar situation.
