I am 20 years old and have very puffy undereye bags.I have been concious of my bags since I was about 13.I often do not leave the house because my eyes are puffy, i avoid seeing people in daylight because i dont want them to see my puffy eyes. I rarely allow my photo to be taken because of my bags and i spend nearly all of my money on makeup and creams for my eyes (that still do not hide them).Am i entitled to a blepharoplasty in the nhs?Is this a sufficient amount of mental stress?
