Dear IuliannaSalamand,
You are being too harsh on yourself. Don't let this type of negativity control you. You are worth all of the happiness in this world like everyone else. It's natural what you are suffering from, these things happen to teenagers like you because of the hormonal changes. That doesn't mean it's abnormal. It is completely normal and happens with every teenager. The difference is that some are able to cope with it and some are not. But you have to be strong and if you want you can consult this psychic, Martine voyance online. She will help you and give solutions to your problems. Go to her official website (http://www.martine-voyance.com/). All the best girl.
