What are the chances of getting diagnosed with excoriation disorder?

Reddit is not the bests place, I know. But I just want some suggestions.

I am 14F, I have been picking my skin (fingertips) since like 5 years old

I have this thought of smoothening out my skin until is is perfectly smooth, no bumps, and I can slide my fingers across it.

I have been thinking about trying to get a therapist. Tho I haven't tell my parents anything about me wanting a therapist since all they told me is "watch out for it", "try to stop" or "distract yourself"

But if I am going to go to a therapist, what are the chances of me getting diagnosed with excoriation disorder/ dermatillomania? There are no lesions on my fingers, just small small wounds and some excess skin. However it causes shame to my daily life where I constantly worry if people will see it, or what if I touch people and they feel my finger is weird or rougher than usual
