FormClosing event in C#

I'm doing a C# app with multiple Forms, like Help, Feedback, Register, Login, etc. I try to override the FormClosing, like when the user presses X in the upper right to close the form, to return to the previous form that was opened.

I tried something like this

private void QuestionForm_FormClosing(object sender, FormClosingEventArgs e)
{
            this.Hide();
            HelpForm help = new HelpForm();
            help.FormClosed += (s, args) => this.Close();
            help.Show();
}

but when I press X, only the Question Form closes, and the Help Form that let's say was the previous one, shows up like 0.1s and the whole app closes.

Acoording to the comments, We can find the solution to this problem is to use ShowDialog.

You can use this method to display a modal dialog box in your application.

When this method is called, the code following it is not executed until after the dialog box is closed.
