Bohot pareshann hun. Mujhy smjh nahi arha kya karun. Mera namaz me dil nahi lagrha, me wazu kr rhi hun to lagrha hai galat kiya aur wazu sy pehly bohot bar puri bismillah parh rhi hun qk mujhy lgrha hai k mene glt parha. Aur namaz me bhi ase horha hai. Dil bhi nahi lagrha aur lgrha hai galat parha hai to bar bar parh rhi hun. Bataein me kya karun?

This is the disease of waswaas and in order to get rid of it, don't pay attention to any of your doubts, pray your namaz quickly, keep something as a sign to help you with number of rakaats completed. You will also need to contact a counselor to help you with bringing this under control
