It's not about the end of the physical world.
There is a huge planetary change going on right now. Many people are experiencing a lot of exhaustion, even as we have problems sleeping, while we integrate all of these changes. Absolutely nothing to fear (except for those people who fear The Light). Lots to be excited about.
is it the planetary change that affects us?
we are being transitioned to operate at higher frequencies (there are lots of articles about transitioning to the fifth dimension). I'm not sure most of us can even fully comprehend the details what is coming with this transition - most of us are not yet operating at the frequencies that would enable us to understand - but it is certainly along way from what the doomsayers are promoting.
