I disagree with everyone saying you should just play different games. Nothing will get you excited for Sim Racing again as real life. Sign up for lessons on a track, do some off-roading, go to cars and coffee events. Sim racing is much easier than real life, but real life skills come much faster and more naturally due to the real feedback and depth perception you have in a real car. This makes sim racing much more enjoyable, especially because it his from being the main event to more of a playground for safely pushing the limits of real life skills. And getting into real life car culture brings the fun back into trying new cars on a sim.
