"I only have one friend in real life, and on the internet I don't even have any."
Blatant lies. I know we don't talk much any more, man, but I truly respect you on here. So do twenty-eight (or more) other people here. I've seen Smash Lords who don't have any people on their Friends List at all.
Also, some other people in "Something bothering you?" said this, but it really is no deal what people say to you. Unless it's a serious offense/threat, in which case you should alert someone else of a higher authority.
Listen, at school, I have like ONE really close friend, and even then we're not that close. I always sit alone before school, and with 2-3 other people during lunch. I rarely speak to anyone in a friendly manner, and I don't have ANY extracurricular activities on my schedule, including hanging out with friends.
And you know what? I really don't mind it that much.
Here's a cool thing to do; whenever you're overwhelmingly upset about something, just do something that immediately relaxes you, be it listening to music or playing video games..... Don't even give a care in the world about anything else. Just take a little time to blow some steam off, or you could try talking to your close friend/a relative about your troubles.
