Is it normal to constantly think about the world?

I do this too. I get deeper and deeper into this philosophical stuff and it becomes all consuming, to the point where I completely block out the outside world. Then usually I end up thinking 'what's the point? We're all going to die anyway!' Then I feel depressive and wallow in an angry, mardy hole for a few days!

So, I'm not sure whether it's normal or not. I guess it's subjective.

You are probably just naturally a deep thinker. My guess would be that something else is the root of your depression. However, I am not a psychologist, so I wouldn't know. Sorry.

SOMETHING IS WRONG HERE....PRAY:)

Of course it's normal, you live in it don't you?

There is something wrong with everyone else, not you. Never allow yourself to be swallowed up with the mundanities of life.

Agreed with Shackleford. You seem half way intelligent.

But no matter what you learn never forget that negativity is useless. Don't allow yourself to go there.

Completely normal, don't dwell on it though, Humanity will soon kill itself off, and thinking about it won't help.
