Having readings was cursing me, so how could I keep doing them for others?

As an ex reader, the amount of curses I unknowingly spoke over people's life's makes me sick. I had to renounce every reading I ever done. It's almost impossible not to see negatives or bad news in a reading, so it was time to stop. As soon as I stopped allowing people to read on me, life went well again. Coincidence, or getting control back?
