hopeless

i feel so hopeless idk what to do. i’m so embarrassed that i let this happen to myself. i’m only on my second day of quitting and it’s so hard. i’ve only been using every day for 4 months but i got myself so addicted in that time idek how to quit. i never got to the 2nd stage but i was throwing up and shaking.
my friend smokes every day and he has no empathy for me he just makes fun of me and says it’s funny. i keep telling him it isn’t funny and im struggling but he doesn’t care??? im hurt. i don’t know who to talk to bc no one understands.
i hate myself so much for doing this to myself it’s so hard not to cave and relapse after just 2 days. i keep thinking “maybe it won’t be that bad if i just take a couple hits” but i know it will and i know i can’t go down that road.
i can’t even talk to my own friends. my parents have been so supportive but im still so ashamed and embarrassed i can’t stand talking to them about it. literally any support will help i just feel so alone.
