You just add to my misery, nothing more.........

Use subtraction instead. 

Is it very logical to leave ideal circumstances, and show up on Earth, and from the first day here, entering into a life of utter misery? As a pre planned life plan?

Not very logical. 

Doesn't suit my function. 

You want a suicide watch? Watch carefully!

Because I'm not hanging around for more tyranny. 

Have you ever watched someone run down the street with the jugular cut?

You will. 

When it all goes dark.
