I've had my braces for one year with another gear or so to go! Train tracks top and bottom.
Like previous poster has said, wax is a must the first time you have them done the wires will really irritate and rub the skin inside your mouth. After a few visits it will harden, I never use the wax anymore. Ask your orthodontist if you can have colours, mine are currently pink 
After the first visit it will hurt a lot but this will get much much better over time. I still struggle to eat anything I have to bite into, sandwiches, burgers etc as the bite is so sensitive but I just tear them into small pieces. There's nothing I can't eat now that I used to be able to eat so far, it just takes a little bit longer 
Most importantly, smile and think of the end results. I am so much more confident now than I was before. I would never wear coloured lipstick etc as I was so embarrassed by my teeth and didn't want to draw attention to my mouth. When they come off my confidence will be over the moon!
For other posters asking how you go about getting them on a budget, mine are actually free! I had a severe cross bite and my adult tooth on my upper left canine never came through. X rays showed it was buried right up in the roof of my mouth, so I had to have surgery to expose the hidden tooth, which was just as gruesome as it sounds 
Springs are used to open the gap and a chain attached to the exposed canine which is attached to my braces to pull it into place. The first photo is the day I had them put on, the second in July of last year. The last set of photos were taken today. In the last photo you can see the little canine tooth finally being pulled into place. To think this was once in the roof of my mouth! The work they can do is incredible!!
Anyway as my case was so complex my dentist put me forward to the university hospital. My orthodontist is a student doing his postgraduate (obviously supervised) and therefore my braces are free. So might be worth asking your dentist!!
Good luck let us know how it goes!!
