Volunteering is a beneficial symbiotic relationship for the vounteer, and those who are receiving help!
Great job on pursuing this important activity. You will no doubt find that when you focus on other's needs, your problems tend to be less prevalent!
You are, of course, also enriching others as well.:)
Churches, community centers, schools, retirement homes, hospitals, ect. always need volunteers to help with various jobs. You can pick the level of involvement that you think that you can handle at first, and work your way into it slowly, until you feel more comfortable.
Here is a link to an orginaztion that also looks good, and places volunteers in various places for helping others.
