I'm depressed because of a skin problem that suddenly came up.

Lately, I've been so busy with work and sleep deprivation that my condition has been a total mess. Every morning, I look in the mirror and see that blemishes that used to disappear quickly now linger for a long time, which is frustrating. Especially on days when I have important events, I inevitably break out, so I don't put on makeup and just cover my face. Even if I meticulously apply concealer, it only makes the blemishes stand out more, and they quickly fade away after a while, which is incredibly stressful. Even expensive nourishing creams seem to be ineffective, and I'm just frustrated. I often feel lost about where to start when faced with these sudden skin problems. I've tried changing my eating habits and drinking more water, but it seems like it takes time to see any noticeable changes. Do you have any skin-calming tips or skincare recommendations of your own? Even the smallest tips would be appreciated, so I'd appreciate your valuable feedback.
