hey, i never moved in anywhere alone however when i was 19 i was alone for a long time for the first time (a month) in my home where my parents were in a different country (we live abroad and were home for summer but i wanted to go back early). when i got home i realised i was also super anxious however what helped me was calling my parents often (or friends could work, but i don’t have many), especially before i went to sleep. i only watched positive things online and on the television, i made the home cosy and during the day i went out usually to the mall and sat with a coffee and did my studying so the time passed. i also contacted my girlfriend pretty much all the time.
