Same here. I'm living in a house with 13 other people and they all have something to do or somewhere to go and no one invited me anywhere. And I dont have a car so I can't leave the house (its a field station, we're all doing research, not just 14 people living in a house. And its not like they talk to me anyway...) I stayed in my office all day today and got myself really down. And I expect tomorrow and Sunday will be the same. You're not alone.
