Kayla, it sounds to me like you lack courage and determination. I'm not going to give you a hard time about that because I'm the same. But if you want some happiness in your life, you're going to have to go for it. I think it's pretty obvious what you need to do. Get that objective in your mind, focus on it, take what time you need to prepare yourself for it. Then do it.
A friend of mine once told me, "You just have to do it!" He was right. You just have to gear yourself up for it and do it. Otherwise, it's not going to happen.
