Sheikh I repent from sins but I struggle to feel regret but I know what I have done is sinful and am not proud of it but I struggle to feel emotion and I worry my repentance to be invalid pliz kindly clarify

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad, sallallaahu 'alayhi wa sallam, is His slave and Messenger.

There is no need for having whispers regarding this matter. Your knowledge of the harm of sins and the danger they pose to you in the worldly life and the Hereafter inevitably entails remorse.

Remorse means that you experience a painful feeling of guilt for committing the sin and wishing that you had not committed it. You undoubtedly have that feeling.

Therefore, you are required to continue to obey Allah, The Exalted, and perform many righteous deeds that erase the sins; for, indeed, good deeds wipe out evil ones. Do not let yourself get carried away with the whispers of Satan, who tries to deceive you into believing that you had not regretted your sins.

Allah knows best.
