Brain Damage?

Okay so this is might be a super dumb question but I am not a smoker at all, but, one time when I was like 13 or so, my friend gave me a bunch of edibles and I had like all of them. I had a crazy experience and it was really frightening. I feel like I haven’t really been the same since. I’m 17 now… Is it possible that this caused brain damage?? Or am I just paranoid. I have seemed to developed ADHD so it may just be a coincidence that this happened around the same time as puberty
