I am just going through the motions

The last few years of my life I have been doing everything a functioning adult is supposed to do. I go to work, go to therapy, take my meds, workout, spend time with my friends and family… but it feels as I am acting out a script. I feel entirely disconnected from everything and it’s been a while since I’ve felt genuine joy. I would never end things; I don’t want to cause any trouble; however, if something were to happen to me it wouldn’t be the worst thing. There no big problems in my life; I could say I am actually very privileged, yet, I feel no satisfaction. And it makes me mad, like how can I be such an ungrateful person? Many people with real problems would love to trade places with me. Maybe I just need my meds to be adjusted or I have to engage in something that I am passionate about, but beating the inertia is the hardest thing to do.
