Come, give it one more chance, wholeheartly. I did the same thing some years ago, just after I started. Became lazy with it and also stopped completely a few months. But then I started again and gradually increased the practice time. Also added some more movements, started playing with the energy, changed music etc. Best thing I have ever done. Now I practice 1 - 2 hours (movements and qigong meditation included) a day. Still some negativity pops up but it does not last. I could feel down for months, now it burns up the the field of higher "qi" much faster. Only minutes now and then.
