postpartum question

Hey everyone :) so I just had my second little guy on the 16th of this month. Well lately I've been going through these hormonal flukes. For example yesterday my husband was messing around and I was trying to clean so I went off on him, and anytime I feel overwhelmed with my one year old and newborn I feel like I'm failing as a mom. So I guess my question is are these emotions valid or am I just overreacting lol?
