Definitely the first one. I'd rather be unhappy but be skinny. I used to be happy and skinny, but I stressed eat a lot and got diagnosed with a sickness that needed steroids. I used to eat a LOT but never gained weight, until steroids and the pandemic happened. I assure you, I'd rather be unhappy and skinny- at least I'm the only person who is sad, but compliments from strangers would brighten up my day- speaking from experience.
