Bleh...emotional out of nowhere

So, tonight was nothing too out of the ordinary. My husband watched football and played on his phone, I made dinner, we ate, I took a shower where my one year old found me and decided he needed a bath too and then played with him after until bedtime while my husband stayed glued to the TV. But through all of it I’ve wanted to cry. For no reason, I’ve wanted to just break down and cry. I dont know if it’s because I’m sober and I would usually ignore the feeling or if it’s just built up frustration from situations at home. Anybody else feel this way? 3 more hours and I’ll have 7 days sober.
