I was filial to my parents, but why does my face look like this...

Taking a good look at my face under the vanity light in the middle of the night, I sigh. Maybe it's because the weather has gotten so cold, but my skin looks particularly dry and dull. My reflection in the mirror feels unfamiliar. Anyway, I wonder why my computer is frozen at this hour, doing a Windows update. Actually, I was just sitting in front of the mirror, feeling proud after giving my parents a generous allowance for the first time in ages. Seeing them happy warms my heart, but my face seems to be losing its vitality, and I feel a little sad. A timid worry creeps in tonight, wondering if I should start taking better care of myself. I've been focusing on cosmetics that I apply on the outside, but I've been too indifferent to the daily habits that radiate from within. I should drink plenty of warm water and eat a balanced diet, but why is it so difficult and tiresome to practice even such simple inner beauty practices? I feel pathetic. How do you all manage to stay healthy from the inside out during the winter? If there's an easy way for me, a timid and anxious person like me, to get started, could you share it with me? Maybe it's because it's late at night, but my thoughts keep going in circles and I can't sleep.
