It's going to be okay. Weed could help, it could also give you paranoia and increase anxiety. It has different effects on different people and in different situations.
It will definately give you some major paranoia and anxiety, if you smoke at some ghetto in front of a bunch of gang bangers.
If you choose the right enviroment though, the worst thing that could happen to you is laughing your *** off at everything that you see.
