Consequences of changing your destiny?

[ethereal]

What happens if you use your free will to choose a different destiny or life plan than your original one?

In that case, all the predestined events that was supposed to come about have now changed. Does a new set replace the old ones, or is everything wiped out and you have pretty much free will over your own life? Even your Higher Self / spirit guides won't have any answers for you, since your destiny is now completely different? They'll still guide you based on your current trajectory, but besides that, you're on your own? Also, what about your previous karmic obligations, are you still supposed to fulfill them, or do they not apply anymore?

I have the feeling that my current destiny and life purpose is completely different than what I chose to be born with. I did some muscle testing and confirmed it was true. It would explain a lot of issues and disconnects that I'm having in my life right now, almost as if I'm living two different lives at once, where the old karmic obligations no longer seemed to apply, but they are still in my life. Would I still have to fulfill them, in that case? Or is it best to just start becoming independent and lead my own life, and leave everything else behind? Is there a point to asking your guides and/or trying to figure out what your life purpose is, if you've already gone and changed it?

Thoughts/suggestions appreciated
