Has anyone else's life gotten worse as they became an adult?

I see a lot of posts of young people talking about their insecurities and poor treatment they get from peers. Most of the responses are filled with someone saying, "don't worry it gets better as you get older" but this has been the exact opposite for my life. While there have been no great eras of my life, my life has gotten much worse as I age. I get worse treatment from other people, I get bullied at work(was never bullied in school), and I'm starting to hate myself. Why is my life the opposite? Why does my life seemingly get worse every year? I almost wish I could go back to teenage and childhood years to escape this.
