Take a break if you have to, but don't cut yourself off. I've felt that way on many, many occasions and you as well as many others here have seen my up and down moods and the times when I wanted to totally isolate myself yet not be alone. The internet can be lonely...we don't actually "know" anyone, the "friendships" are distant, and it's easy to feel disconnected from the real world. But, at the same time, it's a heck of a lot better than actually BEING alone....and you DO belong, as well as anyone here....
