JEALOUSY/FRIEND PROBLEM? PLEASE HELP!!!?

I think this is just a normal response by young girls in high school. It is ok that you are having the feelings and its normal. Just remember that jealousy is such a waisted emotion. You sound like a very bright girl and you shouldn't let this bother you, it is a problem when you become attached to friends and start to feel threatened if they make new friends. This si a normal part of life, people will always have more than one friend. This is probably a phase your friend is going through and if you let her know its bothering you or you are jealous she is likely to use it against you. Why don't you try making a new group of friends or just try harder to like the new girl to your twosome. It wont be long and you will graduate, please don't wait such wonderful years worrying about things like this. I was like you and worried about losing friends to other people so it made me try hard not o make them mad or upset with me but I regret it now. You should remember you are number one and most important don't be unhappy and don't put yourself in arrangements that make you uncomfortable! Good Luck! I think if your friend is a true friend she will come around but you should NEVER expect to be someones only friend.
