I don't mean it in a bad way, but I think you are putting too much stock into this Panache psychic! She doesn't even sound like a real psychic, no one on this forum or other forums even knows or cares about her so I doubt she will be able to do any harm to you.
Just have faith in your goodness and know that what's meant to happen will happen! She can't do or change any of it. And whatever happens will be for better as everyone says.
If you even somewhat believe in law of attraction, then you know you are attracting negative just by thinking negative. So, just clean your energy, let this Panache psychic go from your system and life. Just Ctrl+Del her forever!
Know that someone higher, much much bigger than her is there and protecting you!
Enjoy your vacation and the time you have now because you can't change what's to come but you can make good memories today!
I wish I was on a vacation!!!!!
