My mom said my sh was "mild"

Bitch what?! She has never seen my cuts and I told her about it years ago when I just used nails. Sure it's not like I am chopping my arm off but who is? She literally said that, "moderate would be like breaking an arm and severe would be like chopping limbs off" those weren't her exact words but very similar. By that scale most people would be practically not doing anything, like "extremely mild". I don't think any self harm should be put on a scale like that. I cut to styro almost everyday, often multiple times a day. I am not "mild".
