How can i get a girlfriend and some friends?

Wow! You're only 13 and you have alot of angst. You have along way to go until you are an adult. I suggest that you stop focusing on girls and friends and put that focus back on school work. Or else you're gonna end up doing alot of things to impress others and that is such a bad habit and will leave you feeling empty inside!!! Spend time with people because you enjoy them, not because they are "popular". I would rather have a best friend that's "invisible" than a whole group of popular people that "put up" with me. SCHOOL LIFE ISN'T EVERYTHING! There's a whole world out there, so study and hang out with kind people and you will see that the years flew by and then you will go out into the world prepared and equipped.
