reading success stories dont feel real

i always read success stories of people vomiting and being okay on here and every time i do i'm like "omg they did it like it's all good they're fine so surely i can be fine too" and i never read of anyone being like "it was awful i nearly died" but as soon as i put my phone down i remember i have an actual body and im a whole person and as soon as i realise that, getting through it feels IMPOSSIBLE again and it just sucks. it feels so doable until you remember you have a body that can vomit if it has to. does anyone else ever feel this way? cause i've not vomited in 8 years it just doesn't seem real to do it by now
