As a foreigner, how can you overcome feelings of exclusion in the workplace?

Hello! I'm a working professional who has been working in Korea for almost a year now. I currently work at a kindergarten in Gangnam, and while the work environment and management system are great, I feel isolated among the foreign teachers. One of my foreign colleagues once yelled at me, and since then, they have been excluding me from conversations and even taking group photos without me... These little things have been adding up, making me feel like I'm not being treated equally at work. I've thought about whether this is due to visa issues, but I'm wondering if anyone else has had a similar experience of struggling at a good job because of a few colleagues. I'm curious about how to handle this kind of situation. I'm seeking advice from other communities in Gangnam and talking to friends, but it seems difficult to find a solution within the workplace. If anyone has had similar experiences or can offer advice, I would really appreciate it!
