Think back to when you were learning to drive.
You could steer or you could change gear, but not both at the same time. Learning to fly is a bit like that. Eventually it will click.
Don't pay a whole lot of attention to those who tell you that the expense is the same after you have your license - it isn't. For a start you don't have to pay for an Instructor to be up with you. Secondly you don't have to fly from a licensed aerodrome in an aircraft maintained to Public Tranport standards. Lots of people do, but it's certainly not mandatory. You don't even have to learn in that environment, you could get a PPL(M) flying from an unlicensed field on a Permit aircraft.
On the other hand, if you're not enjoying the experience don't let your pride get in the way of calling it a day. Do it because you enjoy it, not because you are trying to prove something.
