Insomnia...
The most overlooked problem out there.
For the people out there who have Insomnia, I sympathize.
I have had Insomnia as long as I can remember.
The worst is when a person doesn't believe it's a problem. Well to them it isn't a problem because they don't have to live with it everyday.

Insomnia changes my attitude and it also makes it harder for me to think. Physically I tend to feel wore down from it and sometimes it causes me to feel a little more depressed.
