When have you, yourself, felt like you were homeless when you clearly had a home and loved ones?

In fact, in real life, I am a homeless person. The correct point is that I have no home, some times, especially when the mood is not good, feel that I live in this world are redundant. I long for a home, but I do not have, a woman married out because the in-laws is home, but when things are not, feel that the family will treat you as outsiders, but back to my mother's home, but also feel like an outsider, so this feeling of homelessness I often have.
