We normally escape from a tall when it is either unpleasant or to overwhelming to handle. Do you think something like that might be happening? Are you feeling low all day, losing interest in even fun activities, suffering from disturbed sleep (lying awake for hours at night) and disturbed appetite (not feeling like eating or eating as a form of comfort)? If the answer to most of these questions is yes and it has been like this for more than 3-4 weeks, I think you might be going through a depressive episode. Have you faced something recently that triggered these symptoms? I would suggest that you inform your parents immediately, try to explain to them that you want professional help. The faster you can seek help, the easier it would be for you to get this under control. I’m suggesting going via parents because you’re still a minor and parental consent is essential. Do take care and all the best!
