Maybe you should try to stop fretting so much about how many friends you have and don't have in your area. You can do things that interest you and enjoy your life without constant companionship. Stop doing things with the express aim of making friends, it puts too much pressure on yourself. Do things just to enjoy doing them, eg, fishing, horse riding, painting, swimming...anything. Doing something you enjoy, and as I say, doing it purely for your own enjoyment, not to immediately strike up friendships,will make you feel so much more confident and happy. And once you actually begin enjoying life you'll find it much easier to make friends.
We've all felt lonely, evey single person in the world. It's up to you whether you choose to enjoy life anyway or wallow in sorrow because your life isn't exactly how you want it to be.
