How do I change my health bar to be text only

I want my health bar status to be in a text number . I have some code here :
public enum Positioning {
Left,
Right,
}

to

public enum Positioning {
TopLeft,
TopRight,
BottomLeft,
BottomRight
}

Just make an integer to represent your health and follow this tutorial Updating Unity 5 Text Elements with C# Scripting (Basic Tutorial) - YouTube

As @Addyarb mentioned, your post does not make any sense.

The title of your question is How do I change my health bar to be text only which has nothing to do with positioning.

As I am already aware of your code from previous questions you will need to add something like TextOnly to your Theme enum, like this

public enum Theme {
		Bar1,
		Bar2,
		Bar3,
		Medieval,
		Horror,
		Medieval2,
		Scifi,
		Heart,
		Cyber,
		Fantasy,
        TextOnly
}

Next you will need to modify the rest of your code to handle this new enum value to display it correctly.
