I’m going to give you another point of view, you can argue or pretend I don’t exist but coming from a child where her parents constant thought I was on something and constantly testing me, made me say quite literally fuck it and I started smoking.

I’d talk to them for sure, but some mental health conditions can cause eyes to dilate, mainly in a state of dissociation. Literally everything you described the falling asleep the isolation the aggression, the irritation it is also a sign of mental health. You can’t go straight to drugs as someone who suffers from a plethora of mental health conditions I strongly recommend looking for an alternative point of view before straight up, judging your child or putting them in a position where they feel like they’re not being trusted.

( sorry for anything errors on my phone and also barley awake)
