i have a technique i use for unwanted thoughts. i have a door at the front of my mind and one at the back of my mind. the thoughts come in the front door and the only attention i give them is to notice them long enough to escort them out the back door. they are like clouds drifting through. i do not become attached to them, the only thing i think in my head is "thats it, out the back door". i will even visualize the thought being thrown out of my mind like a bouncer throwing a drunk out of a bar.
