If this isn't askTRP worthy please say so and I will remove the post.

So I'm studying abroad in Armenia. The main reason I am here is because back home in cali I smoked weed and my mom didn't want me to smoke weed so she sent me here. We agreed that I would stay a semester see how I liked it and make a decision regarding my return henceforth.

Well I have decided that once the semester ends I want to return. I have made it clear multiple times. She does not want this and tries to convince me to stay, today she issued commands, saying stuff along the lines of "no, you're staying, im not someone you'll toy around with" (idfk, my guess is i can't toy with her emotions and return with the possibility of smoking weed again).

How do I convince her RP style that I will not tolerate her leaving me here. I can't just go full ape-shit but that's what I feel like doing. I have rational reasons but I don't feel that they will make any difference. Her trust in me is degraded as over the past 3 years I said I would quit smoking multiple times but failed to do so. In her eyes this is the only way and she feels she is being a good parent by forcing me to stay here.
