Sheikh, sometimes when falling into sin, I can feel not worthy to be on the path of seeking knowledge, questioning one self how can I be a student of knowledge if I fell into it since students of knowledge should stay away from sins. What is the remedy for such feeling sheikh?

We are all that man akhi everyone makes mistakes and sins, if we didn't why is repentance and making istighfar legislated then? Never ever think like this and know that your repentance is not nullified because u fell into the same sin over and over as it is a mistake that u want to quit, and u can renew your tawbah.
