Just diagnosed with ARFRID, worried about relapse

ello there, i was just diagnosed with ARFRID this August (Aug 29). I was about to start school, on my first day I vomited in the morning (that’s usual for me, i’ve always vomited when i got overly nervous), but then it turned into an everyday thing, then into a twice-three times a day thing. I lost 8 pounds in one week. my mom took me to the ER when i started to get dizzy. I was moved to the hospital for three days. they gave me meds and stuff, but I’m worried i’m going to have a relapse. i’m getting nauseous in the mornings and evenings again. i’m not eating as much as i was before, and i’m nervous that this is happening just because i was doing so well. that’s probably really stupid but does anyone else relate?
