With all this nauseous amount of information getting in the brain, some kind of mental cleansing is needed. Forcing yourself to patiently observe simple activities works for me. Taking a calm walk in a park/forest, cooking, doing physical exercises or whatever else suit you. I also meditate if my head feels like a boulder, it does help, but if you're going for it - make it regular, otherwise you'll just ineffectively grasp the small portion. >>20
Being with a bunch of people doesn't really mean you will feel less lonely. I can only have fun with few close friends. I don't even know if I want to be around others. Besides, not everyone who's alone is lonely. It's a matter of perspective, I guess.
