Dark Circles Around My Eyes

~I wake up in the morning with very visible dark circle~ 

I think I get enough sleep, but I still get the dark circle. Fatigue? Maybe. I googled what cause the dark circle. I found this.

What is causing the dark circles under my eyes?

1. Heredity
2. Allergies
3. Sleep deprivation
4. Oversleeping
5. Eczema
6. Stress
7. Skin becomes thinner
8. Iron deficiency
9. Minor trauma
10. Crying 
11. Lifestyle
12. Fluid retention
13. Skin pigmentation abnormalities
14. Excessive exposure to sun
15. Age
16. Excess salt in the diet

Maybe I have sleep deprivation or oversleeping. I'm not sure but it is not heredity. Maybe stress? Hmmmm, I don't want the dark circles. I look like my mother when I have it. No offend to my mother. It means I look old with the dark circles.

It is okay if I look cute like this, but I look like an old lady. Dark circles are a no no for me.
