Could this be postpartum depression, or am I just overwhelmed?

Hi everyone, I’m a new mom to a 2-month-old baby girl, and I could use some insight. I’ve gotten pretty good at figuring out her cries—she’s not a big crier overall—but sometimes she has these cries that sound like she’s in more discomfort. They’re harder to settle, and every time it happens, I feel this overwhelming urge to cry myself.

It might be tied to when she was born. She had to spend time in the NICU at just 2 days old and had a nose tube put in, which was very tough to watch. I was comforting her while they placed the nose tube, at their first try it came out through her mouth and they had to try again. Her cries now, when she’s upset or uncomfortable, remind me of how she sounded back then. Could that be why I’m reacting so emotionally? I’m wondering if this could be postpartum depression or if it’s just the stress of being a new parent. Has anyone else experienced something like this? How did you handle it?

Thanks for any advice or thoughts—I really appreciate it!
