Anorexia is ruining my life

I’ve lost my period for 1,5 years now, my hair is thinning every day, my relationships with my parents are ruined, i have no friends, all i do is obsess over calorie intake and working out, my day circles around only these two things. I hate how i look, but i would NEVER want to go back to my old self. I have no idea how to get out of this, my psychiatrist and psychologist have tried everything to help me, but nothing works. Every recovery ends a week later and i start restricting again. I just want to be pretty and love myself. I am so scared that i won’t be able to have kids, but my weight loss desire is stronger.
