Its actually rather simple...stop smoking for a while shithead!...

Smoking everyday keeps the mind in a haze, and even though it is usually an anti-depressant, a common side-effect from heavy use is depression/anxiety.

I know what you mean...and I've been there...so trust me, if you stop smoking, your thoughts will stop...Can't you just stop for a while you friggin crackhead?

It doesn't make you crazy, but it can make you think you're going crazy.

(Yes, I'm being comical...but its serious information....listen to it!)
