If you are asking me, you are asking a person who should know. I do not have any friends, and I never go out unless I have to (work, family). I stay in my pitch black room the rest of the time. Is it bad? Well, it depends on what you think. According to the Holy Bible, yes, it is bad, as it says "It is not good for man to be alone". But, if you're like me and don't believe in good or bad, you can just do whatever you want. Of course, looking at how you asked the question, you probably do believe in it. Other than that...being alone all my life I am miserable, don't know what happiness is, feel like no one will ever understand me, I have no confidence whatsoever, no self-esteem, no hope, no purpose... you get the idea. I have tried to be with people more often, but when I do, I feel even more alone.
