What do i do if i'm homesick, but i'm home?

I was on vacation last week visiting my home country(colombia). I came back on Sunday and i have been depressed ever since. I call every day to see how they're doing, and i cry almost every time i call I'm not embarred to say it. I miss my family and the friends that i made in the short weeks i was there. I do have friends here but its just that life isn't really going the way i want it to for me. What can i do i feel that everything i do makes me sad...
