If a tree falls in the forest, but no one is there to hear it, does it still make a sound? Does it matter if no one is there to hear it fall? I am sure it does to the tree. The tree was living and breathing. It's life was cut short or it died a natural death. It now feeds the animals, bugs and microorganisms that will feed upon it and in turn who will procreate further life on and on and on. The tree matters to itself and to all the other forms of life that used it for their nourishment.

Does the alone individuals life matter? I think so. To the individual themselves, life can matter. Whether that individual is very unhappy and cannot see the value, that is a different matter. It is not a matter of the individual's worth but a matter of can that individual see the value in their own existence.

Try to talk with someone if you are this individual. You are probably very well making a difference in people's lives whom of which you have no idea.

Being lonely and being alone are two different things. Being lonely is feeling isolated and hurting or just being sad without others to relate to even though you may have family and friends. Being alone, you can be very happy with your own company even though you are alone.

If you are this person, talk to someone, a counselor or friends. Write down your abilities and accomplishments. You will start to see that you have many things going for you and that your life has value.

I hope this helps.
