I am the music minister within the group of which I have been encountering jelousy, self and nit picking within the group especially since having a real spiritual singer on the team leading on some sundays. There is just one person who has been stiring up strife within the group, she has been giving a bad attitude in rehearsals and complaining outside of the rehearsal other than to the right person. There is just nothing that pleases her, if I give her a lead she usually messes up and when I correct her she takes it personal. What should I do in this situation?
