Regression analysis

I have a classmate in college who shared to me that undergoing regression was that expensive which will depend if a teacher or a professor who will perform the process. Anyway, regression is like a thing of looking back with the past life through some processes. She then asked me the reason of why I wanted to undergo regression. So, I told to her my reasons. But as a psychology student, she advised me that I need to look back at my past experiences and see those things that keeps on flashing in my mind which would result of my negative attitude or negative reactions with those things that I hated most. Once I did, I learned of why I became hateful with those things and those persons. To sum up, I was so thankful with that friend of mine in sharing to me the simple tip for me to heal myself slowly in which I didn’t need to under that expensive regression analysis!
