Postpartum anxiety

I struggle with anxiety as it is ( health anxiety to be exact ) last year after I had my daughter I had real bad anxiety ( everyone said it was probably from Pitocin. ) well I just had my son on the 11th & im getting hit with horrible anxiety yet again.. I’m constantly scared something’s going to happen to me. Like for instance my heart rates in the 60s and I’m panicking, checked my blood pressure a couple times and one was a regular reading another was higher & then another was low then was back to normal.

What can I do for my anxiety ? Does anyone else deal with this? When should you worry about heart rate ( resting ) and blood pressure?! I’m absolutely terrified and I think also it hit me hard cause I hemorrhaged during birth and was afraid I was going to die so..
