My son is in a bad mood when he goes to the army. He felt depressed. How can I convince him?

That's right. It is because you think the army is so beautiful that he thinks it is the most enviable place described in the TV series. As a result, reality gave him a hard education. In fact, he regrets now, regretting his naivety and blindness, so he can't adapt to the rhythm and hardship of army life and has depressed thoughts. The only way is to persuade him: come when you come, don't worry. If you make a mistake, you must take responsibility. You can't escape when you see difficulties, but you should face them seriously. I endured two years and came back from the army. There is no way to expect that the higher you go, the heavier you fall. At the beginning, the troops were imagined too beautifully, which led to this situation.
