Anyone have any ideas on how to help this?

So I have OCD where one of my obsessions is texture, I’m constantly biting and picking my nails which makes them slightly jagged on the edges. If I accidentally brush a finder against an object that creates a feeling of my nail dragging across (usually fabrics) I have to keep going and going with the same action until the feeling is “perfect”. I’ve been dealing with this for a while and it’s getting very frustrating. Does anyone have a similar thing or any ideas on how to help it? I’m trying to stop biting my nails but I’ve done it since I was a baby, it’s hard to stop. Love you guys <3
