To add to what TesTeq and mcogilvie so utterly awesomely have said:
To overcome anxiety, you need to boost it's opposing force, which is courage. You have to find the courage.
However, if you are lying to yourself on your lists, all the courage you master to tackle that list is ultimately in vain. And you subconsciously know this. Even if, again you are lying to yourself about it, you subconsciously still know that your list is not your real list.
Now, the solution to this cannot be to shuffle your lists and calling this a "hack". The solution is to be courageous enough to be honest with yourself. And that is damn hard.
