Quinze, I do not believe simply agreeing with you that the schools you have attended and the instructors you have had are 100% to blame is doing you any favours.
Yes you may have been unfortunate in your choices to date and most here will sympathise with you on that score. However, to get to 36hrs and have to come to a forum to be advised to go talk to the CFI does leave one questioning your train of thought.
The intention is not to berate you, but actually to help by simply telling it as it is. You can choose to take the advice in the interest of making progress and getting your ppl, or you can continue to point the finger of blame in other directions, continue to wallow in self pity and ultimately give up, as you have indicated you may do!
I recommend the former for 2 reasons:
1) the years of pleasure you will eventually get will very quickly dilute the experience to date
2) in years to come you will regret quitting.
Best of luck.
