Does anybody know:

1. Why, when it comes to taharah, I am overridden by such anxiety that all rationality disappears and I begin to think the carpet, slippers etc has become napaak?
2. Why, despite making firm resolutions to adhere to the sunnah, I still take so long to perform wudhu, ghusl, istinja etc because of immense fear of cross contamination?
3. I do dhikr whilst performing wudhu and read the dua before entering the toilet, yet the anxiety is overwhelming
4. The question of 'what if it is still napaak' is so powerful that it consumes all logic and rational evidence.

I am becoming despondent by new taharah doubts everyday and can no longer distinguish between that which is rational and that which is irrational.
