I cant see how anybody could be offended by your post rather I would feel that most would be sorry to see that you have given up.
Those of us that choose to fly aeroplanes for a living have a genuine love of what we do. From charter to regional to airlines we all face the same struggles to make it up the career ladder.It is not an easy road but the rewards certainly are worth the effort.
Dont be in a hurry to give up. Take a step back and think of where YOU want to go and how you think you may get there.
The lack of progress you talk of is not nescassarily your fault. If it helps, just because someone has qualified as an instructor it does not make him/her a good TEACHER. I have seen many cases where a change of instructor has done wonders.
Email me if you like and I will be more than willing to chat about it with you.
