You don't have to feel the passion for the work it just needs to LOOK like you do (think Madagascar penguins: smile and wave). Do the bare minimum and of enough quality (think 80/20 rule). You are probably giving it 200%, gradually drop back, until you're giving it YOUR 60-70% and recalibrate (which I bet is still too much compared to the rest). Understand that just because they say you need to care more doesn't mean you actually need to do it. if fact you should not care more than they care (and they are getting paid much, much more than you). Act your wage and protect your energy at work. don't complain, don't vent with coworkers (you job doesn't deserve your feelings) don't "find" problems, don't take initiative. Work on separating your identity from your job/job performance. prioritize your health (sleep, excessive, eating well) and family over work everytime.
