Irrational fear of loss

So I’m 36 weeks today and I’m having this irrational fear that something wrong will happen to the baby. I know it’s irrational because all the tests came back fine and low for abnormalities but I have this fear that something will happen to him at any point.

SIDS is stressing me out too and we aren’t cosleeping. He will be in his crib in our room but I’m deathly afraid I’m going to lose him somehow.

Am I going off the deep end or is this normal FTM jitters and do they ever go away?
