What to do if doctor asks about drug use and you smoke weed?

💓 • Momma w a 13 month old 💙

I live in an illegal state but I smoke some and recently I’ve been having some bizarre symptoms and I feel I need to go get seen by a doctor. My only concern is I smoke weed mainly to help my anxiety but I don’t have a medical card so I just buy off one of my friends. I have a son but I don’t smoke around him or when he is with me, only when I feel I need it. I know I have to tell the truth about using weed but my mom said if I tell the doctor I smoke I’ll get my kid taken away from me. My symptoms are getting worse and I can’t wait until the weed leaves my system, what should I do?? I’m really stressing myself out over this 😕
