A feeling of depression experienced after finishing a series of anime. PADS for short.

Symptoms include constant thought of the anime, very deep insight, ignoring the people around you, and feeling drowsy.

Some causes:
Being too attached to the characters
Being able to relate to the anime (For example, high school focused anime)

When a person suffers from PADS, they usually long for the life they had to be like the anime, even though they know it will never become reality.
