weird obsessions with baby

Ericka

I am currently 24 weeks pregnant and I find myself obsessing over my breathing because if i don't breathe my baby won't breathe or if she kicks too much I get horrible anxiety because in my head she could be strangling on the umbilical cord and she's kicking for help? I don't know how to not obsess over these things honestly I wish I could relax but I can't I hate it. anyone else ?
