Thats the same way I feel about my scars. I take really good care of them with oil and moisturiser and vitamin cream and supplements. And beecause of that they are fading kinda well. But I don't want them too... Fading just makes me, its not a word but,

. And I don't know why. Maybe because if they fade, its like none of this ever happened. Like it wasn't real or it didn't mean that much. Like what I went through and am going through was nothing.
Seeing them fade makes me plan. I look at places on my arms and trace where I think I should cut, and how deep I have to go to make a scar comparable to one of the none faded ones I have.
Its like, aslong as I have a still healing injury, or prominant scar, the urge to SI again is lessened. But once its fading its out of mind, like it never happened, and then I need to renew it.
Sorry, bet that probably didn't help

What I was trying to say before I started rambling was that I understand what you mean. Maybe somewhere in my ramble theres something that may help you understand why you feel that way about them.
