You are so very young to accept being unhappy but I do understand how life can be as a teenager and TRUST me it will get better. Always remember that you can be and do whatever you want in your lifetime. Don't concern yourself with so-called "friends" because you will meet so many interesting and kind people that will be a TRUE friend in your life's journey. Just be always be yourself and be a leader not a follower and you will see how many people will respect you for that. BE HAPPY sweetie....life is beautiful...it's just your own preception of it!
Oh...by the way I'm crazy about a Taurus guy that's how I came across your post...LOL!
