I learned to drive a car pretty late as well, I think around 21. I was beginning to think that I would never do it, so I forced myself to start learning again. I was really put off by the lesson rates and never strung more than 5 or 6 together before. I had passed my theory already and had been riding a motorbike for 3 years, so had good road awareness, but I was much more nervous doing my car practical test than I ever was on a bike. I had one moment where I thought for sure I had failed, but I passed with only 7 minors and that was pretty much the best day ever.
More recently, I got help when I needed it instead of ignoring advice and not talking to anyone.
