Hi again...DechanDawa: (I just finished replying to another of your Threads.) I'm probably not the best person to reply to this Thread because I am completely solitary, by choice. But that has not always been the case. My perspective is that people become friends because they share common interests. This is not to say that everyone who shares common interests is going to be friends. But, among the "universe" of people with whom you share common interests is where you will be most likely to find friends.
Having said that, my thinking is that the best way to find friends, & gain social support, is to become involved in some sort of group social activity that is of interest. This could be doing some type of volunteer work, joining a club, joining some type of religious or spiritual community or organization... anything that puts you in regular contact with others with whom you share common interests. Also, the fact that you are helping others & working to improve your community & the lives of others is pretty-much an accepted remedy for depression.
What one does doesn't have to be allot of hours per week. And the type of thing one does can often be tailored to meet one's needs in terms of the amount of public contact one experiences. This may, of course, vary depending on where one lives. If one lives in a rural area, the opportunities may be more limited. In a metropolitan area opportunities will be more varied. Where I live, there is actually an organization whose objective is hook potential volunteers up with other organizations seeking volunteers.
So if I wanted to get out & be more social, what I would do is to find some type of volunteer work I would be interesting in doing. In fact, I think about doing just this from time-to-time. In my case, though, overall I seem to be pretty content to remain solitary.
