YES! Summer camp is amazing. You will make tons of friends there (I always have and I'm really shy at home). It is good for you to get away from home, even if it is only a week. The food at camp is usually good and they will put you in a cabin or unit with girls your same age. You can make new friends at camp so you aren't sitting around all lonely at home waiting for them to come back. If you want to go to camp with your sister, then you should try a day camp. Day camps have all the activities as an overnight camp but you sleep at your own house during the day. Either way, day or overnight, going to camp is great, it is something I really enjoy and if you have the option to go then you should take it.
