You may be an out going person and you don't go out much. Your life style doesn't match your personality, I think that is the only reason I can think of... go out more, to have fun.

Sometimes it happens to me too. I am not alone, but I am lonely. If you are alone, that's the reason why you're lonely. You should find some friends. If you are not alone, than that feeling should pass soon. Try to distract yourself, find a hobby or something.

Because you want to. I mean, there are so many people walking on this planet earth that I asume it would be impossible to feel yourself lonely unless you want to feel so. I mean think about it, there are bilions of human beans on this planet. I`ts just impossible to feel yourself lonely, don`t you agree?

Open your heart.Go out often.meet up with friends.share your opinion ,thoughts.there are lots things need you to focus in.if u found something interesting go ahead, let this feeling slip away.

feeling of being lonely is all in your mind - you're allowing loneliness to conquer you. If I say that "Anyone can be happy even if he's/she's alone?" would you believe me? We are in control of our emotions and it's up to us how we drive it. okay, just 'keep your mind open' and learn to accept new things that would be essential to making you happy. :)
