My mom made a joke about self harm

My mom saw a cut on her wrist and said i dont know how that got there, looks like i had some suicidal ideation lolollll. I dont know if she meant it that way, but i dont like how she assumed self harm = suicide, and blantently joked about it when she knows i struggle with it.

(edit: A random person dm'd me about weirdly suggestive and sexual content involving me after making this post, but approched it with helping me. Be careful of who you talk to on here!!)
