I feel you man. I think I'm some ways I might be in this exact spot. I don't know exactly how I'm gonna get out of it, but I think the first step is to reevaluate your goals as a musician. Once u do that, kinda take a look at ur skills now and see if they are on track with your personal goals.
Another thing that can help is to explore different types of music other than the style you currently play. Just learning new things can help reawaken that love that you lost. Anyone else with some more good advice, please feel free to share and be a blessing to your fellow musicians.
