Feeling like a crazy bat

Woke up irritated at the world. My husband was so loving, attentive and playful and I began nitpicking and fighting him over random and (some) stupid shit! Then we fought. I sad some mean stuff. Then I cried and then made him tear up, and then I started laughing to lighten up the situation and told him sorry a million times. We will get past this but I am not ready to feel this unstable for 6 months. Any advice?
