Baby blues or something else

I am 3 weeks PP, and my mind is all over the place. While I don’t think I have PPD, I believe I have a serious case of baby blues or idk what. On a daily basis, I’ll sit and cry over how much I hated my birthing experience, I’ll just replay everything that went wrong and I’ll weep. I’ll get upset at how everything went wrong. I’ll read about women who had wonderful births and I’ll cry. I feel like most days I am just going through the motions of caring for my baby (I am not sure how to explain this. Like I haven’t fully come to terms that this baby fully depends on me? As if I am still in the acceptance stage). I thought people said you’d forget about your birth and just be thankful for your child (which I am) I am not even sure where my feelings are coming from. Nor do I know how to really explain them. I thought they would go away and I’d be back to normal soon. But I am still dealing with them.
