Have you ever felt so low even though you have things together?

I have a partner and a well paid job but sometimes I feel so empty. I think about having to spend the vast majority of my life for the next decades at work, doing things I don’t enjoy, trying to fit in somewhere I don’t want to be and taking orders. The money is good but it comes with a lot of extra stress and responsibility. I’m not even materialistic so there’s very little enjoyment to be had from it, I don’t have a lot of time to use it anyway and I’m tired during the limited time I have. I try to put the money towards early retirement but even being frugal this will take so long. Life seems kind of futile. I feel like I’m trapped and subservient to people who can give me a paycheque. When I reflect on how society is set up it seems there’s no freedom. And the limited amounts the corporations allow me are subject to agreement and when it’s convenient for them. I need approvals. Sometimes I feel so mixed up in my head with nihilism. I don’t know what the purpose of anything is and what I go through to survive and earn a living deprives of any freedom to live to begin with. 5 days a week I’m owned by someone else and there’s commute times on top. At work there’s people who don’t work and just chat rubbish and look at their phone below me and above me there’s people I can’t take at their word and who are combative to suggestions or clarifications.
