There is a big difference between being bored or depressed,
however they appear the same in an adult,
and so boredom becomes confused with depression.

The longer you are bored, the more you will think and appear to others to be depressed,
If it lasts too long, you may eventually become depressed,
but in fact you are bored.

Children are easily entertained, and so boredom does not last long, 
because it is short lived, it does not turn to depression.

Adults start to get bored at some point in their life, 
due to circumstances which are difficult to change because of obligations that come with the search and acquisition of a ‘normal’ adult life.

Often we deliberately choose certain situations because we see some need or benefit from it,  and that new situation soon becomes boring too.

For an adult to claim they are bored is not socially acceptable because they should be, and usually are, so busy with their family and work etc.
You can be very busy, but bored with what you do.

We deny the boredom because its cure is to make a significant change, which is too traumatic for the family, or yourself.
Staying the same, boredom grows into depression.

Trying to cure depression when it is in fact boredom is like trying to sew a patch on worn cloths with a nail, it only makes it worse.

When we find ourselves depressed, it is wise to first look at what is exciting in our life.
If we find nothing, then boredom is the cause.

The cure is a drastic change of attitude, understanding, location, work, hobby, etc.
Each person must find their own way.

But a cure cannot be had until the real cause of the mental state is TRUELY acknowledged,
and then corrected.
