Depression & anxiety. Pls suggest.

I was having depression & anxiety from long time. Recently I went for a 10 days meditation course called vipassana. It was absolute amazing. All my depression & anxiety is gone completely. All negativities evaporated from the body in the form of continuous bubbles. But, similar bubbles are still continuously coming out of the area in the chest till diaphragm. It is very delightful to see these bubbles going out because it is releasing the pressure with every bubble. I had tightness in chest. But this bubbles are loosening the chest. What worries me is that it has been 5-6 days that it is still continuing. It is not getting exhausted. I don't think it is gas problem because it is very pleasing sensation. Don't know if it is any other issue. Pls suggest.
