WHY DO I EXIST
Because your dad and mom had sex
WHAT IS THE POINT OF LIFE
There's no inherent, grand "point", the meaning of life is whatever you ascribe to it - whether that's personal happiness, helping others, changing the world, etc.
WHY HAVEN'T I KILLED MYSELF YET
Only you can answer that. Humans do have a biological drive to live, though, and that's why most really depressed people are still alive, probably.

WHY DO WE DO ANYTHING IF WE ALL KNOW LIFE IS A SLOW, MEANINGLESS MARCH TOWARDS DEATH!?
See the answer to the "point of life" question. We do things that make us satisfied, that make us content and that we enjoy. Death is the end of the book, but why you need to skip ahead? You're not even on chapter 3 yet.
IS HAPPINESS EVEN REAL
From personal experience, yes.
