I feel neutral about her, but she has good reaction gifs. I dislike the Kardashians but I use a lot of reaction gifs that have them in it, too.
I don't think so. You can have self harm scars, for example, and in that case self harm would be an adjective. Either way, "commit self harm" still is incredibly awkward phrasing when self harm itself is a verb and can be used by itself.
