It’s not a complete false hope. See point 4.

By itself moving to a new country won’t change the core of who you are. But it does give a good opportunity for change. It helps a lot if you are able to set aside some time to reflect on your interactions and experiences. For me a big catalyst for change was paying attention to why I was doing things. Was it just out of habit or because it was what I know? Or was it something I really want to do?

Funnily enough being more social is one of the big things that changed for me. Partially because I found a group of friends I like, partially because I came to understand what I want out of being social. Also what my limits on socializing are. But all that took effort. In the form of both in finding friends and understanding myself. It also wasn’t quick. Probably took me 2-3 years so give yourself plenty of time.
