Practice to channel energy

I guess if you have regular yoga practice, you will always feel like you gain some energy after the practice. I recently realize in fact, it's not about "gaining energy", it's more like "channeling" the energy!
As I said I have been feeling confused and jammed, mantally and physically, here in Tainan. I feel anxious and get irrated very easily, which I even don't like myself. This has been not only making myself small, but torqued, I think. I even forgot and forgo my practice, I just let go... But, it only gets worse. I finally pick up my mat and began to practice again. I feel MUCH better and RELEASED afterward. Then, I realized, the energy within me (including emotion) just needed to be channeled out! It's like the water in the vast, need to replace with fresh water frequently!
I need yoga practice, I need more meditation as well. I should add this into my new year resolutions!!
