I had braces as a teenager, like at least half my friends, so I don't need them now, but I can think of three people off the top of my head who had adult braces, and all of them much older than you.
One of them was my own dentist. She was doing a trial run of lower braces only, on the *inside* of her teeth. It's a technique used in Europe but not much yet in Canada. Her brother, an orthodontist, was using her as a test subject. An outside observer could not see the braces, but she could feel them against her tongue. It made her lisp a little. When I asked her how it was going, she said pretty good, except that she'd lost ten pounds because she'd stopped snacking between meals! When you have braces you have to clean your teeth every time you eat, so she said she ended up only eating at mealtimes, because it's such a hassle.
Another one was a friend I've known since elementary school. He had crooked teeth as a teenager but refused to get braces, and his parents didn't force the issue. As he got older his teeth got a lot more crooked and he regretted his stubbornness. At 38 he bit the bullet and got braces. He just got them off a few months ago, shortly before his 40th birthday. He too complained about the hassle of having food stuck in his teeth all the time. He hated the whole process for that reason, and left the braces on only until his teeth were reasonably straight. His orthodontist wanted them on a bit longer.
The third was a guy I worked with about ten years ago. He hated his receding chin, so he went in for jaw surgery as well as braces! They severed his lower jaw on both sides, slid it forward, and bolted it with metal clasps. Yikes! Then he had to have his jaw wired shut for three months. I remember him saying he was getting awfully sick of milkshakes. I don't remember him complaining about stuff stuck in his braces, but honestly, I think that was the least of his concerns!
Anyway, my point is, you're not alone. It's a bit of a hassle, but it will be worth it when it solves you jaw problem!
