Prana;
You are right about your thoughts but in my humble opinion you need to just relax and ride the wave as far as it will take you. Nothing lasts forever. But here and now can be forever.
I was taught also that the Universe began with a sound, it was the sound of Soooo.
The phrase "So What" was kind of a joke on creating the Universe. "So" the Universe was created and "What!" big surprise!
Enjoy being Happy it is a path with all the rewards you could ever dream of.
