I'm absolutely miserable 24/7. Things haven't been good for the past 3 years. On weekends il sleep up to 14 hours a night and on weekdays il find myself restless unable to sleep. Ive almost completely withdrawn socially, I used to be friends with just about everyone at my school but now I feel polarized and like I have nothing good to say. Every day at lunch I sit at the table with my friend group of like 15 people while they eat and il just listen to them talking. Most of the time I can hardly make out what their saying and when I do hear what they're saying I have nothing to contribute to the conversation. I can tell they're getting sick of me. I've stopped talking to girls also. 

Despite this however, whenever find something even remotely funny or amusing or whatever, or whenever I find myself feeling even a modicum of pride or gratification il find myself grinning like a complete idiot without any control over the matter. Like il see a friend unexpectedly and Il approach them with this big dumb grin as if I'd just received the best news of my life. Recently I've found that whenever something like this occurs I can bite my tongue as hard as I can to distract me. This went too far however as I've bitten a hole in my tounge by accident . Whats wrong with me man
