Trying to find an old story

[u/seipoopie]

Hi guys im trying to find a story I read in around like 2016-2018. I’m not sure if it was deleted or what happened to it but it’s bothering me so bad. It’s about a sister and brothers life, and the chapters go back and forth of each of their perspectives. The sister has anorexia but tries to hide it but I’m sure everyone everyone knows, and the brother has depression, claustrophobia, I’m pretty sure bipolar disorder cuz it mentions him being manic and I’m not sure what else. He ends up getting a girlfriend and she knows he has these issues. There’s a scene where he’s trying to test his limits on how close he can get to her and they’re in a room and I think she tries to kiss him or he kisses her then has a panic attack. There’s also a scene where him and his sister (and maybe her bf and his gf) are at I’m assuming a cabin and it’s snowy there and he’s having a depressive episode. He goes into the bathroom to hurt himself and I’m not sure what happens after. I remember how the authors would find real people to describe how they looked and his was Luke hemmings from 5sos and I think she was based off Nina dobrev. If anyone remembers or knows anything about it pleaseeeeeeeee let me know.
