What should I do for aura cleansing and healing if meditation makes me feel sick or heavy?

I tried meditation and chakra work, but instead of feeling peaceful, I felt heavy and even a bit sick, so I had to stop. It was like something negative was blocking me from going deeper. What should I do for aura cleansing when meditation seems to make things worse?
