The Great Wall
At times in the life of a bi-polar worry becomes a wall. All encompassing, treacherously high and heavily fortified, it is a wall that does not fail to lock you inside, away from all of life.
There are certain tactics that you can use when you encounter this worry wall, and any or none of them may reap you success. For instance, you can attempt to carve or find one small foothold after another with desensitization and counter-conditioning focused on the topic of your current worry. This is a long, arduous task and you must be careful not to look upon the way you came, for it puts you at risk for falling back to the ground at square one. Another way to get past it is to simply bombard through with your stubbornness and willpower. This is a definite test of character and only the stoutest can erode the fortifications, even a small amount. You can look for a door or a window by visualizing all is as it should be, and all will be as good as it can be. This works well if there is in fact, a soft spot in the wall, willing to open up and permit you back into the world. You can try to move the circumference of the wall circling you by attacking one fear at a time, slowly gaining ground. The danger here is that you can lose ground too as new worries become obsessive instead of abating.
In the end, you have to figure out how you will deal with your own wall and hope that those close to you understand that you are not distancing or isolating yourself to spread dismay. You pray that they will rather understand you are trapped. Although it may seem vaporous in nature, it is as real and solid as any wall ever erected. It is uncomfortable and real, in spite of the fact that it is easy to dismiss these global fears unless you are the one experiencing them.
