What is the way back to acts of obedience and to get rid of the whispers concerning Wudu and prayer, given the absence of righteous companionship and the fear of hypocrisy?

Worrying (waswasah) is an illness that must be striven against and overcome, and wasting prayers is among the gravest sins. Sincere repentance erases sins, and the one who repents is like one who has no sin. Among the ways to attain steadfastness and strive against the self are: contemplating God’s attributes and death, frequent remembrance (dhikr), seeking knowledge, self-accountability, keeping company with righteous women, joining da'wah (Islamic propagation) activities, and frequent supplication.
