Ayyee. Weed is a psychadelic.
If your having underlying(s.p?) coarseness in your life or a bad head-space then she will circle around those things. Is there some things your possibly neglecting in your life? Any big changes in your life kind of recently(any deaths, moving, new school, graduation, new job, getting fired, losing a chick, even finding a chick)?
A good way to get back in good with smoking is learning how to "ride the waves" I call it. Finish everything you have to do in the day. Call up only your best of true friend(s). Put on a good movie/album whatever entertains you guys. Grab a bowl only fill it half way. Take a hit but stay focused on what your doing, not that your smoking. Pass it be a gentlemen/lady! Smoke at a SLOWER pace than you normally would. You been smoking blunts, bongs, steam-rollers lately?
Weed is alot like hallucinogenic drugs. After a bad heavy trip you don't wanna drop another ten-strip or munch up a fatty quarter of everybodies favorite fungus. You wanna ease yourself into a situation where you can be comfortable again.
Use cannabis more of a reward verses "just what you do". If you praise her she'll praise you.
Smokers anxiety is not uncommon just most guys are afraid to admit when their freaking out or w/e. Ride the waves, though not everyone is surf-able my fellow adventurer, so sometimes it's not bad to chill on the beach.
Anxiety in my opinion is a LOCKING device on your mind. Say your gonna go party with some new people or something. You get all stoned and end up sitting in the corner alone because your just so caught in your introspective worm-hole of a mind. When you should be out surfing the crowd

. So in whatever trip your having be it weed, or w/e you can't let yourself get stuck in an anxious state, and if you realize your in an anxious state you cannot falter. You have to look it in the eyes and LAUGH at it. Cuz everything thats gonna tweak you out is made up in your head. In this case your being your worst enemy. You need to befriend whatever thoughts you are struggling with, or abandon them like a bad friend, get the feel of your board under your feet again. Find your bouyant point.

and let me know what's going on. I have been through this many times.
