S.A.D.

Separation anxiety disorder is a psychological condition in which an individual experiences excessive anxiety regarding separation from home or from people to whom the individual has a strong emotional attachment (like a father, mother, grandparents, and brothers or sisters). Separation Anxiety Disorder (SAD), is characterized by significant and recurrent amounts of worry upon (or anticipation of) separation from a child or adolescent's home or from those to whom the child or adolescent is attached.

I'm no longer a child but still I experience such. But sometimes you have to let others go (a best friend, a loved one). So here i remain but life goes on.
