why don’t i feel hungry

i don't feel hungry anymore, it's like i've lost the ability, i don't need food, it feels like. i don't enjoy the taste of food anymore. i don't feel hungry but i feel starved if i don't eat for a while. i think my bodily functions are stopping one by one and i'm going to die. i need less and less sleep, i need less and less food, am i just doomed to live life as cardboard? when will i feel real emotion again? i need help
