Accept your choices and refrain from squandering time on ruminating, especially when it comes to an insignificant person. Once you stop caring, all issues will resolve themselves naturally.
Why should one be concerned about others' opinions? How others perceive you is of little consequence. What truly matters is how you view yourself.
Just follow your current rhythm: avoid checking your WeChat Moments, refrain from playing games, and maintain a regular sleep schedule by going to bed early and waking up early.
