Need some advice!

My husband and I have an amazing relationship. Except for the fact that I have terrible mood swings. Everything will be fine and then it's like my brain has no filter and I can say the worst things... This morning for instance, instead of asking for him to take out the trash nicely. I straight up said "Take out the trash when we get home." I can be so callous and he is ever so patient with me. We'll fight about it every once in a while. But I feel like I'm not even myself, I know I can be the sweet adoring wife that he married, but I have trouble taking stock of my own emotions. We've been together for almost 7 years. Married for 2 tomorrow. Do any of you ladies ever have these issues or am I just crazy?
