You know, mood swings, crushes, love, it's all part of growing up. Don't be surprised if you are perfectly happy one minute, and then you want to cry the next. It's perfectly normal, but don't worry, you can conquer that easily! When these "Mood Swings" hit, get something cold or warm to drink, whatever makes you relax, take a few deep breaths, and settle down. Relax, watch a movie, read a book, watch tv, do something to get your mind off your body. Tea works great, sometimes some Milk is a great solution. You usually need to settle down, because it's just hormones trying to take over you body. Now, If you have a crush, there's not much I can help you with. You just have to act normal around them, don't act all shy or anything, because they might think you are strange. Treat them just as you would any other person. Remember, Have a good time, be carefull, and have fun!!
