Here are a few options for the post tag description, depending on the nuance you want to convey:

**Option 1 (Direct & Concise):**

* **Description:** 對自身能力、價值、或決定感到懷疑的情緒。 (The emotion of doubting one’s own ability, value, or decisions.)

**Option 2 (More Explanatory):**

* **Description:** 探索自我懷疑的根源，包括在工作、人際關係，或個人選擇中遇到的懷疑與不安。 深入探討如何克服這些負面想法，培養自信。 (Exploring the roots of self-doubt, including doubts and anxieties encountered in work, relationships, or personal choices. Delving into how to overcome these negative thoughts and cultivate self-confidence.)

**Option 3 (Focus on overcoming it):**

* **Description:** 了解自我懷疑，學習應對策略，重新建立自信，並在生活中做出更果斷的選擇。 (Understanding self-doubt and learning coping strategies to rebuild confidence and make more decisive choices in life.)

**Option 4 (More poetic / thematic):**

* **Description:** 一個心靈掙扎的標籤，關於內心的聲音如何質疑我們的價值，以及如何找到克服懷疑，成為真實自我的道路。 (A label for a mental struggle, about how the inner voice questions our value, and how to find the path to overcome doubt and become our true selves.)

**Key Considerations:**

* **Target Audience:** Who are you writing for? Casual readers? People seeking support? This will influence the tone.
* **Post Content:** The description should align with the content of the posts tagged with “自我懷疑.”
* **Keywords:** Consider including related keywords to improve SEO, such as “自信” (confidence), “焦虑” (anxiety), “情绪”（emotions), “克服” (overcome).

Choose the description that best suits your blog’s style and the specific contents of your posts! I would personally recommend Option 2 or 3 as they are more action-oriented and offer concrete information.
