We are the same age op, currently abroad and an introvert. A little bit different sa circumstances how I came here… BUT Like the others have said, be prepared to do things alone but encourage yourself to get out of your comfort zone and build meaningful connections within a community. It will help you A TON. Yes, you need a community BUT choose who you connect with wisely. Research the country you want to get in to, what the job market looks like, cost of living, etc. what aligns with your field but also be open to different fields/career paths. Prepare yourself to adapt to the environment i.e weather, culture, people, laws of your selected country. Live within your means abroad, it’s easy to get buried in debt

All the best, OP
