Once you have realized you have taken something too far is there a way to go back?

I was warned by my professor that the subject matter I choose can affect my view on life. I did not realize what they meant by that and just continued on making whatever I enjoyed.
Now I have made a truly objective piece of art and it is disturbing me because I feel like I have desensitized myself in ways I could not have imagined when I began work on it. I want to make more but am fearful of the impact the work may have on my life. I do not want to describe it for I do not want others to think the subject matter is interesting and want to make one for themselves. Lets just say it involves a massive amount of nasty pornography and only the naughty bits. Now I realize this it is easier to deal with but still haunts me. Any ideas? What to do?
