Lots of triggers follow, probably. Mostly for dermatillomania (skin picking). I guess if you didn't like that cuticle-peeling scene in Black Swan you'll want to scroll on, scroll on, scoller~
I wish I had vaned feathers somewhere on my body so that I could pull them out of my skin whenever I'm nervous or irritated. This is a little unusual because I don't have any emotional compulsions relating to hair or its removal from my body. I do bite my skin, though; like, I'll take little strips of the skin at my cuticles and knuckles in my teeth and bite them right off. For the most part I don't feel any discomfort because I'm just taking the dead upper layer, but if I accidentally pull a longer piece than I intended and it starts to go really deep, it will indeed hurt like the motherfuckest thing. Unfortunately I can't stop and leave pieces like that. Even if I bandage them up, I'd know they're still there. And now that I've written all this up, it occurs to me that I've been a lot better about this lately! All my fingers used to be red and bloody during high school and intermittently through university, lmao, and people would ask what happened and I'd get kind of pissy and lie. I never understood why they asked, really. My hands look like they've been chewed. Before I tell you, please guess what happened, Sherlock. Then again, it's probably only in the head of a serial skin-eater that "oh I did it to myself" is the obvious answer.
Anyway, the feathers. I absolutely wouldn't tear them out. EVER. I think I'd be pretty vain about them and literally preen quite a bit, ahahaha. In times of stress, however, I think it'd be so terribly soothing to take a few, one at a time, by the quill and pull them out of their follicles very carefully. I'm sure this would be an uncomfortable process in general, but the act of removing them seems like it would be worth it. Depending on how many I had, I almost definitely wouldn't pluck them all at once. I imagine I'd want to leave some, either for cosmetic purposes or just to remember exactly how they look and feel.
.......WHY WOULD I EVEN HAVE FEATHERS.
Celaeno is my spirit guide. Eating stuff, grumping about carnival witches! Admittedly I am neither immortal nor caged for the first time in my dread existence, but I'm working on that.
