Hi mate
You are only young, your whole life will be changing around you.
You don't know what pleasures life is due to bring you, there is a special person waiting out there for you who will make you complete. We always think it is the first person we fall in love with but this often not the case.
Please don't give up, be strong, and you will look back at this time in your life from the future and be glad you stuck with it. What doesn't kill us only makes us stronger.
If you're feeling really bad, please goto the doctor and speak to them to see what help you can get.
Take care, best wishes
