As a person who has suffered from bouts of depression in my life, I know what it's like to feel "down" for no reason. It's actually kind of annoying when this feeling takes over because many times you don't even know why you feel the way you feel.
There are many ways people with this "disease" I guess I'll call it learn to cope. Society provides MANY forms of escape from drinking to drugs to sex to gambling (my vice) to entertainment in all it's different variations. There are literally thousands of diversions.
I don't think choosing a diversion to help you overcome feelings you don't understand is necessarily a bad thing if said diversion isn't really causing harm to your well-being or the people around you.
As a matter of fact, I've personally found that doing the opposite of harming others or yourself provides the best sort of relief. Occupying your mind and time with HELPING others actually ends up helping YOU feel better in the end. Like you've done something worthwhile. Which you have!
So if you also suffer from feeling sad, lonely, depressed, anxious, just not right, or whatever at times possibly think about someone other than yourself and how they might need your help. How I do it is by surfing the web for sites like VolunteerMatch.org or Voly.Org, etc. Believe me, once you start the search for people looking for help, it's not hard to find them.
Even just starting to think about helping others can stop the anxiety and give you a sense of calm.
Anyway, try it and lemme know if it works for you too. I bet it will!
Peace to you. :-)
