At your age some mental disease can begin to manifest itself. You may want to go get mentally evaluated and find out where you really are mentally. It maybe you have some underlying mental disease and you may need to check it out. Especially while you still have medical insurance with your parents.
The underlying disease may in fact be treated very well with cannabis. There are a couple that are not. You want to find out if you have some sort of mental disease or not. A sativa might cause those symptoms, but it IS what you'd want for depression. You may be 'overthinking' this a bit.

The pot wouldn't make you that way, if you already came that way. It would enhance it!

I know many with IQ's in and above your range. Pretty fun conversations when stoned. IQ and mental disease is a 'mixed-match' of opinions.

It seems this may indeed be exactly as killerweed said, 'Strain related.' I'd test that out. I'd definitely do medibles and try.
When you get to Amsterdam and you don't feel like, "I am going to get caught!" I have a feeling most of those symptoms will go away. Or the coffee shop or where ever you are, will know which blend to give you. Be sure to be open and 'blunt' with your information. Get the proper mix of strain for yourself and enjoy the heck out of it.

Take small doses. Know, you do not get all the effects at once. I've had some hybrid lately that kicks you about a minute into the smoke and knocks you into a chair about 20 min. later! If your heartbeat is up, most likely you got a really good sativa. It is not unheard of for mmj to raise your heart rate. It will not, keep it up. Your mind can do that for you. There are ways to bring it down and your doc did not seem concerned. I would not be either.

I believe that mmj enhances our sense's and we 'zero' in on those things that alarm us mentally. You've probably watched a TV program that did the same thing. But, didn't notice because you were involved in the program.

:thumbsup:Enjoy Amsterdam and send in a smoke report of everything you try! I've heard nothing but good stuff! Have fun! :jointsmile: pr:rasta:
