Postpartum Anxiety

Before I had my baby I had a slight anxiety issue but now that he’s here I feel like it’s gotten really bad. I don’t trust anyone with my baby even though I know they’re fine. If anyone is holding him I’m staring them down like a hawk the whole time. At night I stay up late worrying about it I’m doing a good enough job. Does the anxiety ever go away? I can’t even leave my baby with my MIL (who I love and trust) for 3 hours without worrying like a freak. My son is 4 months old.
