I felt probably like a Hikikomori when I moved to the other side of the country for my now ex and worked remote for two years. I basically never left the house except for walking the dog and doing grocery shopping. I had no friends and no real social life except when my ex and I visited her friends and family or if I flew back to my hometown.

Even as an introvert I felt fucking miserable for the entire time. I enjoy solitude but that shit wasn't it, it was isolation.
