EATING DISORDER

Hello, for the past year or two I’ve been noticing a large decline in the amount of food I’m eating and my appetite and now it is to the point where I am never hungry and i hardy finish the one meal I’m eating at night, I’m just not hungry and I can’t even force myself to eat even though I know I need to or even if I feel bad, when I try and force it I feel like a bubble in my throat and genuinely feel like I’m gonna throw up, I’m just feeling really concerned and feel like it’s at the point where it could be considered an eating disorder but I just don’t know what to help, I know malnutrition can be really bad for your body and i think im starting to feel the effects daily even
