Homesick

Don't know why recently missing my family, feel like want to go back to stay for a period, but due to my work, I can't back frequently. This year is fourth year I am staying outside, I haven't been homesick heavily before, really want to stay at home for long period, gathering with my parents and brothers. Maybe I face problems and stress from outside, need a shelter. I read a article last time, it mention that our family is a shelter for us to rest and avoid stress from outside, after staying in my home for my first 20 years, now only I truly experience it!!! I start to realize how treasurable for people who has a complete family with love. Family always is the first!!!
