Getting married is more stressful than most brides would care to admit. It is pretty normal to find that you end up tearing your hair out because you cannot decide on which unique wedding favors you are going to choose and if you want chocolate cake or fruit cake. Then worrying about the hair that you pulled out!
Seriously speaking, getting married should be a wonderful time. It is not worth getting stressed about it. Take it one step at a time and enjoy every moment. After all, it is not everyday that you get married. Enjoy it and relax!
