Hi Nacho:
Welcome to the mystery of life!
Don't be too quick to blame QiGong. Just because a few things go wrong you need to keep an open mind. Perhaps there is a basic environmental problem where you live (Feng Shui) or your horriscope is a low energy day. Usually our expectations and busyness over ride all kinds of messages we are receiving but we are so wrapped up in our daily drama that we are unaware of the need to change course. Perhaps there was something you were meant to be doing and all these things were happening so you would become aware to take care of that important business. Take deep breaths and relax. Tomorrow is another day. Don't kick the dog. But do be mindful of him/her and give more love. It will come back ten fold.
Good Luck!
Agent B
