有时候会觉得很沮丧。

When you feel like you can't control your emotions, it's important to remember that it's normal to have ups and downs. It's also important to find healthy ways of dealing with your emotions. For example, you could try deep breathing exercises or mindfulness activities such as yoga or meditation. Talking to a friend or family member about how you're feeling can also be helpful. If the problem persists, consider seeking professional help from a mental health professional.
