Starved (2005)
I was definitely way too young to watch a show like this (in 2005 I was 15 or 16) and I don't doubt that some of it crept into my subconscious, along with all the other 90s/early aughts eating disorder media we had to contend with.
All I remember about this show is one character having a normal conversation on the street with someone and then puking into the bushes after he was alone. Truly messed up, no wonder it got canceled so fast.
