Hey Nikola, yes I'm sure your family will be concerned, but better to tell them and have them help you get the treatment you need. It's not so uncommon to feel like this when we're depressed. But getting help can change the way we feel, even just opening up to others helps us feel "not so alone"........believe me my friend, this will pass, you will feel better. Speak with your parents or School counsellor, don't stay alone in your pain.
