I agree I too am alone most of the time.

I found that throughout my career life, I came across people who wanted to be around me as long as they want something from me and then leaving me alone.

So now I made habit of staying alone.

I know it is not good thing but I cant help it as well. I am just alone. It's really hard to have people on our own terms around and then staying alone if we don't accept this fact.

I am in my late twenties (28) and found that though many people of my age have girlfriend or family with kids. I just made myself more lonely over a period of time. I find happiness in small things.

I have pets (budgies) and they keep me from being lonely. Pets do help.

Hope you find someone around to bug you all the time so that you will never get lonely.
