There are inevitably valleys on the road of life. Negative emotions are a stumbling block on the road of life, which is undesirable but sometimes inevitable. Overrepression is not a good idea. What can really help you get rid of negative emotions is to adjust your mentality.
Instead of regretting yesterday with tears, it is better to struggle today with sweat.
Life should look forward. Only by liberating yourself from the past can there be a way ahead. The big house is too big and the small house is too small. There are no shortcuts in life. It tests your perseverance and endurance. As long as you persist for a while, don't bemoan the past, don't waste the present, and don't be afraid of the future. Everything will be under your control.
