From the very small amount of information you've given, it does sound as though something needs to be done. But I'd suggest a change of instructor and/or school, rather than giving up. There are loads and loads of people around who took longer than most to learn to fly, but still eventually managed to sort things out, learn, and earn a living from flying - I should know; I'm one of them! There are very, very few people who really can't learn to fly. There are quite a lot of people who struggle due to the learning environment they're in not being right for them. Many of those give up...I was once asked how I managed to keep going, and what it was that made me different from the ones who called it a day. Your friend and I have determination and staying power - and that will take you an awfully long way in aviation, and in life.
So maybe a friendly chat along the lines of trying somewhere new is in order....though I'm not sure if you're the best person to give it. Maybe you are, but I don't have enough information to know that...only you can decide.
