It is possible that something has happened between you two that is making your best friend angry or upset. Perhaps there is a misunderstanding that needs to be discussed and clarified. The most important thing to do now is to talk to your best friend and try to figure out why they're upset. A simple and heartfelt apology could be enough to mend the relationship. Additionally, making an effort to understand their point of view and taking responsibility for your own actions could help restore trust.
