In the Name of God, the Most High
1- It is necessary to have wudhu (be in the state of ritual purity) for every prayer. If it is extremely difficult to control your bowl or if the very thought to maintain your ritual purity will intensify your illness, you can perform Tayammum in stead of wudhu.
2- Correct pronunciation of the words to the regular extent, which is in fact the acceptable pronunciation, is a basic element and a necessary condition for the validity of prayers. If you are unable to pronounce the words in a standard manner, you should try your best to pronounce the words as correctly as you can.
3- OCD (obsessive compulsive disorder) is a disease or a satanic mood which changes the pleasure of worship into hardship and difficulty depriving him of mental and physical comfort. One should not pay attention to satanic temptations and it is necessary for him to avoid being obsessive. An action which emanates from obsession (wasvas) is haram. The religion has some reasonable solutions to make matters easy. If you act according to the solutions proposed by the religion, you will enjoy the pleasure of worship and religiosity.
