I have noticed that you have been feeling a little depressed recently. This feeling of feeling unimportant and lacking motivation is really disturbing. First of all, I want to tell you that your feelings deserve to be valued, and everyone will have such a low period. Regarding the reasons for taking leave, although I can provide some common options (such as colds, migraine, gastrointestinal discomfort, family affairs, etc.), I would like to invite you to pay attention to your mental health first. Although these reasons for physical discomfort are commonly used, they may only temporarily relieve symptoms, not solve the underlying problem. If you have continued to feel： -Loss of interest in work -Reduced sense of self-worth -Avoid social interaction This may be beyond the scope that ordinary leave can solve. Suggest you can consider： 1. Honestly explain to trusted superiors the need for a "mental health day" (more and more companies accept this reason) 2. Make an appointment with a counselor for a professional assessment 3. Try to write an emotional diary to record the specific events that triggered these feelings 4. Talk to relatives and friends about your feelings. Isolation often amplifies negative emotions. The real reason for asking for leave should be based on your true needs. If you really need to rest and adjust, a simple "need to deal with personal affairs" is also a reasonable explanation. But more importantly, after giving yourself a chance to breathe, take the initiative to face the source of these emotions. If necessary, I can accompany you to explore more ways to alleviate this state. Your current self-awareness is already a good first step.
