So i am 17yo boy. My problem is that when im with my close friends they think i am fun person and if i meet friends of my friends its really good. But when i enter a new place that i dont know anybody i cant talk to someone if i talk im talking like a boring person but i dont want that i want to be like myelf when im with my close friends. I changed school its my second week and its not going really good. Any suggestion? And also how can i be more energetic? One last thing that i didnt have a gf for my whole life now that i lost fat i kinda started to like this girl from another class but dont know what to do.
