How can you beat loneliness in a big city
Adopt a dog from a rescue shelter. This will give you a warm feeling ! Knowing that you rescuded a dog from being put down. but make sure the dog is just able to be a dog. Let him go out side.
Try to join some community classes, or volonteer for the red cross or a hospital that will boost your self esteem, you can mingle and meet people, while doing a wonderful thing.
Pick a nice spot to hang-out and get to know the people who regularly go there...you'll be fine !!
