my best friend started smoking weed about a year ago and it really affects her mental health, I've done everything and just can't make her stop. it's really crazy, i'm pretty sure she's going through an actual psychotic episode every time she's high. And it's starting to affect her even when she hasn't done anything. For example, she's way more anxious and quite a few times hysteric and i don't know what to do. I'm not sure I can deal with this. I'm struggling with severe depression and this really makes me want to kill myself. I NEED YOUR HELP, PLEASE!
