Is Masturbation A Bad Habit?

So a couple of months ago I stopped watching porn and masterbating to it (the only reason I watched it was to have orgasms) I started when I was around 9-10 and stopped when I was 13. But now I am feeling an immense amount of guilt and regret and I feel like I ve ruined my life. I m a girl btw, please help, have I ruined my life? And I feel even worse because I haven t told my parents and do not plan on doing so but I just feel horrible, how could I do this to them? Why would I do this to them?
