Tell me I’m not the only one

So I have my food and bad days , but on my bad days I have this overwhelming feeling of doom because I have to take care of this tiny human that requires constant care every second. I miss my older life when it was my two older independent kids and I could nap when I wanted , or take a shower when I wanted. The anxiety is so real. And I’m taking meds for it BTW. I feel so guilty bc i see other parents and they are sooo happy and excited for their newborn and I’m here trying not to cry. (Again).
