I know how you feel. You think, "will I ever feel like my normal self again?" or "will I ever feel happy?" You don't have to try so hard to fix this. Like I said, this just happened, so you can't expect to get better overnight. It might take a little while, but you will get stronger each day and the more you talk about what's on your mind to others, it will help you even more. I know you're trying your best to be positive, but you know it's okay to cry and feel down. You have every right to do so.
I have had some dark times in my life, and I'm going through one right now, but each dark time I have been has made me stronger. You will be stronger too. Have more confidence in yourself and just take it easy right now dear. If you need to talk about something, then you make sure to let it out. If you want to get mad, then get mad. If you want to cry, then cry. *hugs*
Like one of my favorite quotes says, "Every cloud has a silver lining." ^.^ You will see your silver lining soon dear.
Btw, a friend of mine sent me this tumblr link dedicated to the Disney Princesses (and other Disney movies, but mainly the princesses. XD). Not sure if you have seen it or not, but it's cute. ^^ Might put a smile on your face.http://petitetiaras.tumblr.com/
