Lonesome or lonely?

I am wondering if there's a difference between being lonesome and lonely?

These are findings i got from the net.

I think lonesome is a word to use in place of - sole, only, alone; and lonely would be used for missing the company of another.

Lonesome meaning alone (but not necessarily wanting the company of another) and lonely meaning alone (but wishing for the company of another).

My kind of loneliness:

I think loneliness is  a deeper state, 

than lonesome.

Lonesomeness passes by,like a lonesome mood?

Loneliness is a permanent state?

I'm really not sure about this, but i'm trying to explain

these things just like how it feels for me when i'm on that state

or the other?

That we can find out......later ! :)
