Sounds like you have a bit of burnout? Perhaps some stoic books might help. Ryan Holiday has some nice ones.
1) Not everyone who seems passive is passive. People are more stressed than they let on. 2) What does work mean to you? Do you view it as something that pays the bills? Is it your passion and you adore what you do? Somewhere in the middle? Have you become more engaged because you love what you do or because you feel like you have to pick up everyone's slack? Those are good things to think about.
Some things that helped me (maybe you'll find them helpful too):
1)I literally tell myself every day that this is just a job. That I'm replaceable at work but I'm not replaceable at home. That my work projects don't matter in the grand scheme of things but my personal ones do. That it doesn't matter what my boss/coworker thinks of me but what my family/partner/friends/I think of me.
2) Do the things that you know are good for you. For me that's yoga, running, ballet, playing the violin etc.
3) Have times where you don't discuss work related things with your partner/family/friends (e.g. stop talking about work after 5 pm)
4) Take dedicated breaks. Don't scroll through Instagram and call it a break. That's mindless stimulation. Make a cup of tea. Go for a walk. Celebrate yourself.
5) One of my favorite quotes: "There is no audience to perform for, there is no approval, no admiration to attain. There is no role worth playing, there is no one to convince. Let it go."
6) Think about your bigger motivation behind work. While I don't like my current job at all, I try to view it as a stepping stone to something I want to be doing in the future. Some people find vision boards helpful. I haven't tried that yet but want to do that next year.
7) Your self-worth is not attached to your job. You spend a lot of time at work and it is so important to remember that you are a wonderful, wholesome, lovely person whether you work at that job or not. Sense of self can get lost when we're stressed about work. Please surround yourself with people that just love you no matter what. That hype you up.
Letting go of work stress can be so damn hard but I really found that with some strategies (whatever they will be for you) it does get better. Hang in there! And also, no shame in quitting and looking for something else if you can. Life's too short.
