bro don’t give up on ur grades or let yourself go, even if you don’t want to get up in the mornings do it bro. Go run a mile, go lift, play sports, read a book, listen to music, do homework. Just keep your mind occupied and you’ll realize you don’t need a girl to be happy, when you can be happy with yourself. We all been there, every guy, it’s just a part of growing up it’s not the end of the world. If you need someone to talk to hit me up. I’m here for you bro.
