Your question of who you should contact for communication is a little difficult to answer, as it seems that (before we can offer advice) you aren't real willing to try many possibilities. So, how can we advise?
There are online resources ~ but you rarely have limited access to a computer. Hmmm... That is a challenge.
How about you contacting the 800-service that Bill3 referred to? They are great listeners, and they really do care, regardless of beliefs.
Life
is challenging, for sure.

However, try hard not to assume that everyone feels ____. Some people probably do feel that way. But, not everyone. For your sake, give them a chance. You just might meet some real decent people right there, in your town, after all!

Imo, it really is worth taking a shot at. What do you have to lose? Perhaps you could start with some light talk (ex: about the weather or local schools) with the mail clerk or librarian, most people always love to talk about the weather! Just, keep it light and brief.
Imo, it takes several times of very light chatter before I feel safe enough to move onto other subjects. Personally, it takes me a very long time (many interractions) before I feel safe enough to expose a little bit of myself. However, I'm not within the "norm" of general society either. I am extremely cautious with who and when I will reveal little parts of my self to. Over the years, I have accepted where I am in life. This alienation of sorts has been done by myself ~ I can see that. I have accepted that reality.
Acceptance of the role that I have played in my alienation makes me feel a little better. I have recognized that I am pretty picky about who I will let into my life, so I can see that there is a HUGE majority of people that I will not even t-r-y to connect with, regardless of my loneliness and lack of friends. That is a big flaw of mine. But, at least I can recognize and accept that fact. And, every once in a while, I will do something that is very "normal" in society, but completely uncharacteristic of myself, and be friendly with others. And, I'm amazed by how friendly they are back to me!! It's really something! but, it's also require me to step outside of my comfort zone and put myself out there. Not easy at all. But, it can be done. Trust me.
