I feel so scared

I feel so lonely and scared. I don’t even remember how my eating disorder started. All I know is that I was counting my calories and started decreasing them as I started to not workout as much. Now I can literally see my bones in the mirror. My mom took me to a dietitian but all the dietitian did was to tell me to eat more. Today I wore a shirt without any sleeves and my dad noticed my bones and started threatening to kick me out if I don’t start eating more. I thought my mom would help me and listen to me but all she said was “if you want to look like a monkey, do what you want. If you want to look like a human, listen to us”. I moved a couple of months ago and now I don’t have any friends at this new school that I can talk to either. I feel so lonely and feel so afraid to gain weight and I’m so scared my parents will force me to eat more. I don’t know what to do anymore. Why am I like this
