"Felt too Burmese to be Singaporean"? What the fuck does that even means? Singaporean is not a race, it is just a state of your citizenship.
You can be a Chinese Singaporean, a Malay Singaporean, an Indian Singaporean, or a whatever Singaporean. If you don't feel like a Singaporean, then you should not be a Singaporean.
This fucking clown can just fuck back to Myanmar.
