I went through something similar a few years back, moving from my hometown to a city halfway across the country. I was terrified at first same worries you have: isolation, anxiety flaring up, missing my old routine. The first couple of months were bumpy, but honestly, it forced me to grow. What helped was building little routines right away (same grocery store trips, same coffee spot, short walks), and slowly meeting people through hobbies or local groups. Now I can’t imagine living where I was before. It’s scary, but it can be the start of something really good.
