PP Feels

Just had my baby 2 days ago and I'm starting to feel super overwhelmed. I find myself happy with my baby, she's everything I could have asked for! But I also find myself crying a lot. Idk if it's my pregnancy hormones still acting up or what but it isn't a great feeling. I don't know WHY this is happening. I was told it's something that happens the first few weeks called "baby blues"? Has anyone else gone through this?
