If you find yourself:
looking in the mirror, fixating on what you think is a physical appearance flaw,
And then you are:
preoccupied with thoughts that all other people will see are your flaws, And you start to:
feel embarrassed, ashamed, or self -critical,
And this leads to:
engaging in compulsive behavior like mirror checking, skin picking, seeking reassurance, camouflaging (trying to cover up disliked body areas)- then you may have Body Dysmorphic Disorder (BDD).
Read below why it is important to get treatment for this under-diagnosed and under-recognized disorder.
