It's easy to judge someone life, not having lived it and from the outside. Just realize that life is a Three-Dimensional puzzle which you can only resolve by checking out all the sides!
Have fun, stay out of debt, keep your word, watch less TV, visit your friends, and I can never remember that last thing.... ..Oh yeah, try not to forget the important things in life!
You say you are lonely, you say that you need a friend, you say that no one cares about you; you know, you may be right. But life goes on and so must you, and one day this may no longer be the case!
