You might experience loneliness as a vague feeling that something is not quite right, a kind of minor emptiness. Or you might feel loneliness as a very intense deprivation and deep pain. One type of loneliness might be related to missing a specific individual, either due to death or geography. Another type might be a generalized feeling of aloneness, of wanting contact with other people. You keep loneliness alive and continually a part of your life by not doing anything about it, by waiting for it to eventually just disappear by magic or with passing time.
Loneliness can be a very passive state.
You need to first identify and admit that you feel lonely. You may express the lonely feelings through tears, words, or whatever way feels right for you. Often, by expressing your feelings, you discover the causes or reasons for your loneliness. In discovering the reasons for being lonely, you are then able to decide upon some actions that will begin to overcome or cope with these lonely feelings. Without an active problem solving approach to your loneliness, you could remain stuck and engulfed by those feelings.
