First thing,you are o.k.Second thing no such thing as bad trip like any other drug you have to be ready for it.Now you should smoke a bowl of herb relax & relize that it is your own brain making you have those feelings.As soon as you do you can get on with your "normal life"
Next time make sure to plan your "trip" a lil better,like be around fun loving people.
Just remember the are thoughts YOU came up with & YOU have power to control the stupid thoughts. SO STOP TRIPPIN ALLREADY!
