Ok, this is not a historical question, but I did not know where to put this:
I am 17 years old and I just started to feel too strange for this world. I find my life and this world extremely strange and mysterious. There are a lot of and seriously thousands of questions inside my head everywhere and everything I see. Why did I suddenly become like this?

You might feel this way because something is happening at home, tragedies have happened, sexual relationships, or bad grades. Take a look in your lifetime and see what factors take place in your life.

Consider how they can affect your life. If there is something bothering you, then talk to an adult, or try not to think about it.

If this still bothers you, then just take a deep breath and do something you like to do.

Hope this helps you!
