['So I have been traveling around by myself.  It has been getting to me this week. I miss my friends.', 'What sorts of places have you been going? Alone time is always great but then sometimes it gets to be too much so I understand.', 'I just got to Vietnam. There is no one in this hostel so I havent met anyone to hang out with. Maybe I should move to a different city.']
You could always do that but maybe exploring on your own can give you a different perspective on things.
I have been traveling solo. The last week has been hard because I havent really met anyone. I miss home.
