I'd fully endorse all of the above points, enjoy it, cut yourself some slack. Why do you want to get your PPL? To fly. What are you doing while getting there? You're flying. So, what's the problem?
Fly with other instructors, fly in the right hand seat with other pilots, fly in the back of a four seater. Have some fun, that's what you're in this for anyway.
When you were learning to walk did your parents give you so many hours of practice and decide that if you hadn't got it by that point they should give up on you as you clearly weren't a walker?
If you keep trying there's every chance that the breakthrough is just around the corner and you'll make it soon enough. If you give up, you definitely won't make it, ever.
