I havent spoke to anyone in 4 days..?!

yo brah keep your head up. Im sure your cool, but you just need to get out a little more. Try being more social by joining the gym or community types of organizations. Maybe keep up your hygene a bit too, because nobody likes to talk to a slob (not judging your hygene just tryin to help). If you keep thinking these nasty thoughts and other crazy things, listen to some music or watch a funny television show/movie. A great artist in my opinion for calming you down is Kid Cudi. Im not sure if you like this type of music but some of his songs are really calming (although all they really talk about is drugs) but still. I hope for the best, and have a great day.

I start to feel antisocial sometimes too, so this is my solution

You know what? There is someone you know who is feeling isolated at this very moment. Pick up the phone and just give that person a call and say, "Hey, I was just thinkin' about you. I never do this but I thought I'd call and check in with you..." If they take the cue you can break your own pattern of isolation. If they don't, then maybe offer something of your own struggles and say "do you ever feel like that? I mean am I the only one?" Try to give it a little levity so it doesn't come out scary, but you might find that sharing your own struggles helps to ease the weight of their own. If so, you both gain something from a very small effort. Small things go a long way, trust that it will touch something even if the response you get is not impressive. Force yourself to do this a couple of times a week, even as you pass on the street..."Hey, I've been thinking of you (even if you haven't thought of them until that very moment)...how y'doin'?" Make it the habit of greeting that way and you may find you are deluged with conversation, but you may also find out that there are a lot of people out there just like you, who need a friend. If you want a friend, BE a friend. Be patient, change is awkward.

Ask yourself why you dont speak to people as much as you used to, and whats changed. It sounds like you've secluded yourself away, why not expose yourself to human contact more. Most people are genuine and friendly and they wont judge you.

Not good yo
Get out and involved with something like a group or organization, you'll meet people through that.
