when does the nausea go away

hi. im 20 days sober, and im also a senior in highschool. each day my symptoms have gotten better but i still feel nauseous honestly every day pretty much all day it just comes in waves i guess. its really hard because i have school and i get nauseous at school which makes me super anxious because im worried i might throw up or something. some times its not bad but right now im extremely nauseous and i just feel terrible.

im just wondering when this gets better? i guess i had hoped by day 20 it would have but nope im still super nauseous every day

one more thing: my closest friends all smoke a lot and usually our hangouts consist of us smoking a lot and having a good time, i havent gone over in a couple weeks because i had a depressive episode and then the chs episode on top of that and i guess im just really worried about how its gonna be when i go over this weekend. i genuinely feel like the worlds biggest loser and i just dont want it to be weird because they are all gonna be smoking and high and im just gonna be there looking stupid 😕😕
