From wat u said, tanda2 anxiety atau depression, terutama kalau dah berlarutan lebih 2 minggu. Rasa penat melampau, cemas, sedih tanpa sebab, dan hilang motivasi memang petanda biasa. U can try to talk to someone u trust, jgn pendam. Buat deep breathing and get help from professionals, blh walk in to any nearby kkm. U r not alone ok.
