Oh ok I get why you said it.
Actually something similar happened to me over 3 years ago, I was very very depressed, I had totally fucked up my course and my parents had gotten angry. My father sat me down and I could tell with the tone of his voice and the way he was saying things he was getting angry with my life, coming down hard on me to get me into shape, about to control my life. Then I rolled up my sleeve and showed him I self harmed (even though that wasn't half of what was bad) and it shocked him so much it changed the way he thought about how I felt, it gave me more control back and made him help me get what I needed.
Do I regret saying it and showing him? Well it was very awkward, I had to try and ignore it and bury it from conversation. It felt horrible I did not want this to have come out. But what it achieved was a much better understanding for my pain. I got to move my life in a good direction. Even though it has never felt like a good thing saying what I did in terms of the effects it has been.
So I guess what I am saying is yes you might never feel good about saying it, but it could have a positive impact on your life in terms of the way others now think about your emotions.
