Parents and mental health.

I dont know if I'm selfish for even thinking this but here it goes.

TW

since I was about 12, (I'm 16 now) I've struggled with mental illness and its severed over time. My dad has spoken to and been to many of my appointments with my support team and has been told MANY TIMES that I'm depressed and have anxiety and he has pushed it away. I've struggled with self harm and hes seen them fresh and all my scars and he was there when I attempted suicide and he never showed a care. he's threatened to send me to psych wards for long periods and horrible things. so fast forward, I left home because he hit me and now hes messaging me telling me to come home and that my half sister is depressed and needs our support..... he even gave one of my cats to her ???? (also I've only met this half sister once I literally dont even know her. we dont live togeher)

like why would I come home for that? you dont even care about my mental health and you're expecting me to be here? like I I literally feel like he just wants me home to boss me around and argue with me.

opinions? like isnt this ridiculous or am I overreacting? I need advice.
