As silly as it sounds, a pet.
No matter how you look or how sad you may be feeling, your pet is there for you.
I was depressed and at a very sad point in my life and my dog was there for me. How could an animal be there for you..?
They do say dogs are a humans best friend and they really are. I hit rock bottom and myself felt very depressed and unloved and my dog was there for me, laying beside me and even cuddling with me despite how sad and hollow I had felt inside.. My dog made me realize I am loved and cared about and there is someone that will love me regardless and never put me down.. My dog!
