I was super stressed out from grad school and living with roommates at the time. I didn’t realize I would have an issue living with other people, as I had never done it before. I suppose you could call it extreme social anxiety or something. I was afraid of running into them or them seeing me or seeing what I eat even though they were all nice. I was just weird. After I graduated, I was able to get my own place so I didn’t have that problem anymore.
