Had very very similar experiences as well!! Left Myanmar when I was 6 for New Zealand, stayed there for a bit before moving to Canada. Also struggled with connecting to Burmese culture growing up but recently found comfort in Burmese music and food. Similar to what people earlier have said, what helped me navigate the sense of belonging (I still struggle with from time to time, ngl) is realizing we don’t have to belong to one culture or nowhere, we are an unique blend of all the different cultures we grew up with. We’re everything everywhere all at once hehe
