Also worth noting -- you can do a rev-matched downshift without heel & toe action. More like just toe action. To gradually slow down you can do just the toe part. Simply blip the throttle, downshift one gear, and let engine braking slow the car. Once the revs falls and it's comfortable to downshift into the next gear, do it. Sometimes heel and toe driving is suited to more purposeful inputs rather than casual driving. But there's still a benefit to rev-matched downshifts because they are smoother, safer, keeping you better in control of the vehicle as a whole. Really they are the only way to downshift correctly, anywhere, ever.
Learning this stuff takes time. Be patient and reward yourself with ice cream often. (It'll give the clutch time to cool off, mr. clutchdraggerdownunder!
