Since having a child, I've become different. When my husband goes home from work, the house becomes empty and gloomy. Although I don't have to feel sad. But I miss my husband. Every time I look at the clock, I wait for it to pass quickly so he comes home from work. When he is home with us, I feel so calm and relaxed. Does anyone else feel this way? Or am I overthinking things?
