My mom is just not an empathetic person when it comes to self harm

My mom, is not a great person, I'm an adult now so even while still stuck with her for a while at least she can't control me in that sense.

When it comes to a lot of things she's not great, but whenever it comes to self harm it's always just cruelty or anger that I'm stupid, not that I hurt myself.

She almost views it as laughable or just plain stupidity that I would self harm, even going so far as today after me saying "I don't really want to talk about this with you, when I do you are rude to me or tell me to get over it", to which her response was "Oh? So....what, you want me to feel sorry for you or something?"

I just don't even know what to say, why would someone even ask about something like self harm, then just use it as a cudgel to attack me under the guise of caring.

Just exhausting.
